'MOVE_PM_ERROR'					=> array(

		2	=> 'An error occurred while moving the messages to the new folder, only %2d from %1d messages were moved.',

	),

we need to split this into 2 strings, because we need 2 different plurals:

• %1d messages
• and %2d ... were moved

Broken example: An error occurred while moving the messages to the new folder, only 1 from 2 messages were moved.
Should be: An error occurred while moving the messages to the new folder, only 1 from 2 messages was moved.

Same for:

	'FOLDER_MESSAGE_STATUS'		=> array(

		1	=> '%2$d from %1$d message stored',

		2	=> '%2$d from %1$d messages stored',

	),

Also shouldn't that be x out of y instead of x from y?
