	MORE_PLUGINS_ADMIN_OBJECT
	SPUTNIK Release #4
	
	This plugin compontent is common for all More Plugins (see more-plugins.se for 
	more information about these plugins) and does most of all the heavy lifting 
	that is required when creating, editing and deleting data. This object does not 
	care what that data is, as long as the data adheres to some rules.
	
	SETTINGS
	========
	name - Name of the plugin
	option_key - The key that holds the plugin settings in the _options database table.
	defaults - contains the default values when creating a new data item
	fields - defines the keys that are extracted from $_POST when saving
	file - should always be __FILE__ (so that we can get the plugin directory)
	
	DATA LAYOUT
	===========
	1. 	There is onlye one data array contains all the data (per plugin). Within this 
		array, there are 4 types of data, each with their own key.
		- ${data}['_plugin']
			This is the data actually stored in the options table in the WP data-base
			for this plugin. New data is created here, and must exist here to be edited. 
		- ${data}['_plugin_saved']
			A feature of more plugins is to save individual features to a file, which can
			be exported to other installations. Objects read in from file are stored here.
		- ${data}['_other']
			This is data created in function.php or by other plugins. 
		- ${data}['_default']
			This is data that is native to WordPress, e.g. Post and Types for the case of
			post types.
	
	2. $_GET['navigation'] deterimines the view.
	2. $this->keys is the keys of the data in 1) that is viewed, e.g. array('_plugin', 'news') or
		array('_other', 'box', 'fields', 'title'). As a $_GET['keys'] variable it is imploded with a 
		comma as the separator, e.g. '&keys=_other,box,fields,title'
	3. $this->action determins what is about to happen
	4. $this->action_keys is used when deleting stuff, as $this->key sets the navigation.

	SAVING:
	=======
	- The fields that are to be saved are defined in the $this->fields, which contains 'var' for
		single value variables and 'array' for variabels that can contain array values,
		associative or just normal.
	- Default values for creating new stuff is defined in $this->default. 
	- In x-settings.php	keys that are deeper than 1, e.g. $data['one']['two'] are retrieved
		as 'one,two'.
	- $_POST['index'] sets the last key to save to. This needs to be set in 
		validate_submission() in each plugins x-settings-object.php.
	- $_POST['originating_keys'] defines where the request came from - used to
		see of the name was changed. 
	- For a key that contains deeper levels of data, the entire data contained within
		that key must be defined in $_POST. E.g. for More Fields, the entire 'fields' key
		must be defined in $_POST when saving the box. This is done with $this->settings_hidden(),
		which will seralize any array data.
