new method to get an application-initialized filter driver.

	* camel-session.c (camel_session_get_filter_driver): new method to
	get an application-initialized filter driver.

	* camel-filter-driver.c (camel_filter_driver_new): Remove the
	get_folder function and data args from here...
	(camel_filter_driver_set_folder_func): ...and add this function to
	set/change them.

	* providers/imap/camel-imap-folder.c (camel_imap_folder_new): If
	this folder is INBOX and we're filtering INBOX, set a flag on the
	folder for later.
	(imap_update_summary): Add another argument (GPtrArray *recents),
	and if it's non-NULL, add the uids of any \Recent new messages to
	it.
	(camel_imap_folder_changed): If doing filtering in this folder,
	create a recents array and pass it to imap_update_summary. Then
	get a filter driver and use it to filter the recent messages.

	* providers/imap/camel-imap-summary.h:
	* providers/imap/camel-imap-utils.c (imap_parse_flag_list): Add
	support for the \Recent flag.

	* providers/imap/camel-imap-provider.c (imap_conf_entries): enable
	the "filter" option.

	* camel-types.h: add CamelFilterDriver typedef here
