 * Metadata for configuration manager plugin
 *
 * Note: This file is loaded in Loader::loadMeta().
 *
 * Format:
 *   $meta[<setting name>] = array(<handler class id>,<param name> => <param value>);
 *
 *   <handler class id>  is the handler class name without the "setting_" prefix
 *
 * Defined classes (see core/Setting/*):
 *   Generic
 *   -------------------------------------------
 *   ''             - default class ('setting'), textarea, minimal input validation, setting output in quotes
 *   'string'       - single line text input, minimal input validation, setting output in quotes
 *   'numeric'      - text input, accepts numbers and arithmetic operators, setting output without quotes
 *                    if given the '_min' and '_max' parameters are used for validation
 *   'numericopt'   - like above, but accepts empty values
 *   'onoff'        - checkbox input, setting output  0|1
 *   'multichoice'  - select input (single choice), setting output with quotes, required _choices parameter
 *   'email'        - text input, input must conform to email address format, supports optional '_multiple'
 *                    parameter for multiple comma separated email addresses
 *   'password'     - password input, minimal input validation, setting output text in quotes, maybe encoded
 *                    according to the _code parameter
 *   'dirchoice'    - as multichoice, selection choices based on folders found at location specified in _dir
 *                    parameter (required). A pattern can be used to restrict the folders to only those which
 *                    match the pattern.
 *   'multicheckbox'- a checkbox for each choice plus an "other" string input, config file setting is a comma
 *                    separated list of checked choices
 *   'fieldset'     - used to group configuration settings, but is not itself a setting. To make this clear in
 *                    the language files the keys for this type should start with '_'.
 *   'array'        - a simple (one dimensional) array of string values, shown as comma separated list in the
 *                    config manager but saved as PHP array(). Values may not contain commas themselves.
 *                    _pattern matching on the array values supported.
 *   'regex'        - regular expression string, normally without delimiters; as for string, in addition tested
 *                    to see if will compile & run as a regex.  in addition to _pattern, also accepts _delimiter
 *                    (default '/') and _pregflags (default 'ui')
 *
 *  Single Setting
 *  -------------------------------------------------
 *   'savedir'     - as 'setting', input tested against initpath() (inc/init.php)
 *   'sepchar'     - as multichoice, selection constructed from string of valid values
 *   'authtype'    - as 'setting', input validated against a valid php file at expected location for auth files
 *   'im_convert'  - as 'setting', input must exist and be an im_convert module
 *   'disableactions' - as 'setting'
 *   'compression' - no additional parameters. checks php installation supports possible compression alternatives
 *   'licence'     - as multichoice, selection constructed from licence strings in language files
 *   'renderer'    - as multichoice, selection constructed from enabled renderer plugins which canRender()
 *   'authtype'    - as multichoice, selection constructed from the enabled auth plugins
 *
 *  Any setting commented or missing will use 'setting' class - text input, minimal validation, quoted output
 *
 * Defined parameters:
 *   '_caution'    - no value (default) or 'warning', 'danger', 'security'. display an alert along with the setting
 *   '_pattern'    - string, a preg pattern. input is tested against this pattern before being accepted
 *                   optional all classes, except onoff & multichoice which ignore it
 *   '_choices'    - array of choices. used to populate a selection box. choice will be replaced by a localised
 *                   language string, indexed by  <setting name>_o_<choice>, if one exists
 *                   required by 'multichoice' & 'multicheckbox' classes, ignored by others
 *   '_dir'        - location of directory to be used to populate choice list
 *                   required by 'dirchoice' class, ignored by other classes
 *   '_combine'    - complimentary output setting values which can be combined into a single display checkbox
 *                   optional for 'multicheckbox', ignored by other classes
 *   '_code'       - encoding method to use, accepted values: 'base64','uuencode','plain'.  defaults to plain.
 *   '_min'        - minimum numeric value, optional for 'numeric' and 'numericopt', ignored by others
 *   '_max'        - maximum numeric value, optional for 'numeric' and 'numericopt', ignored by others
 *   '_delimiter'  - string, default '/', a single character used as a delimiter for testing regex input values
 *   '_pregflags'  - string, default 'ui', valid preg pattern modifiers used when testing regex input values, for more
 *                   information see http://php.net/manual/en/reference.pcre.pattern.modifiers.php
 *   '_multiple'   - bool, allow multiple comma separated email values; optional for 'email', ignored by others
 *   '_other'      - how to handle other values (not listed in _choices). accepted values: 'always','exists','never'
 *                   default value 'always'. 'exists' only shows 'other' input field when the setting contains value(s)
 *                   not listed in choices (e.g. due to manual editing or update changing _choices).  This is safer than
 *                   'never' as it will not discard unknown/other values.
 *                   optional for 'multicheckbox', ignored by others
 *
 * The order of the settings influences the order in which they apppear in the config manager
