2000-05-26  Gene Z. Ragan  <gzr@eazel.com>

	All of the below is work in progress on the Files and Programs
	capplet.  I am currently retro-fitting jrb's capplet to use
	our modified capplet layout and new gnome-vfs mime API.
	This capplet does not currently work properly, but does build and
	causes no harm if run.

	* mime-type-capplet/edit-window.c: (ext_remove), (apply_changes),
	(initialize_main_win), (initialize_main_win_vals),
	(launch_edit_window), (hide_edit_window), (show_edit_window),
	(populate_application_menu), (populate_component_menu):

	* mime-type-capplet/mime-data.c: (selected_row_callback),
	(edit_clicked):

	* mime-type-capplet/nautilus-mime-type.desktop:
	Changed entries so capplet would register itself as "Files and Programs"
