/**
* 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')
