/**
 * Contains all the functionality required to be able to edit the core server
 * settings. This includes anything from which an error may result in the forum
 * destroying itself in a firey fury.
 *
 * Adding options to one of the setting screens isn't hard. Call prepareDBSettingsContext;
 * The basic format for a checkbox is:
 * 		array('check', 'nameInModSettingsAndSQL'),
 * And for a text box:
 * 		array('text', 'nameInModSettingsAndSQL')
 * (NOTE: You have to add an entry for this at the bottom!)
 *
 * In these cases, it will look for $txt['nameInModSettingsAndSQL'] as the description,
 * and $helptxt['nameInModSettingsAndSQL'] as the help popup description.
 *
 * Here's a quick explanation of how to add a new item:
 *
 * - A text input box.  For textual values.
 * 		array('text', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
 * - A text input box.  For numerical values.
 * 		array('int', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
 * - A text input box.  For floating point values.
 * 		array('float', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
 * - A large text input box. Used for textual values spanning multiple lines.
 * 		array('large_text', 'nameInModSettingsAndSQL', 'OptionalNumberOfRows'),
 * - A check box.  Either one or zero. (boolean)
 * 		array('check', 'nameInModSettingsAndSQL'),
 * - A selection box.  Used for the selection of something from a list.
 * 		array('select', 'nameInModSettingsAndSQL', array('valueForSQL' => $txt['displayedValue'])),
 * 		Note that just saying array('first', 'second') will put 0 in the SQL for 'first'.
 * - A password input box. Used for passwords, no less!
 * 		array('password', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
 * - A permission - for picking groups who have a permission.
 * 		array('permissions', 'manage_groups'),
 * - A BBC selection box.
 * 		array('bbc', 'sig_bbc'),
 * - A list of boards to choose from
 *  	array('boards', 'likes_boards'),
 *  	Note that the storage in the database is as 1,2,3,4
 *
 * For each option:
 * 	- type (see above), variable name, size/possible values.
 * 	  OR make type '' for an empty string for a horizontal rule.
 *  - SET preinput - to put some HTML prior to the input box.
 *  - SET postinput - to put some HTML following the input box.
 *  - SET invalid - to mark the data as invalid.
 *  - PLUS you can override label and help parameters by forcing their keys in the array, for example:
 *  	array('text', 'invalidlabel', 3, 'label' => 'Actual Label')
