Don't show .desktop files which are specific to other desktop
environments ("OnlyShowIn=foo" where foo != GNOME).

This patch ignores those files at a very low level
(NautilusDirectoryAsync), and for all directories.  It should probably
only do it for ~/Desktop:  the original bug is about not wanting to
show the .desktop files which KDE drops in your ~/Desktop (those files
do have OnlyShowIn=KDE).

2006-05-22  Federico Mena Quintero  <federico@novell.com>

* libnautilus-private/nautilus-directory-async.c
	(is_foreign_desktop_file): Argh, check that the OnlyShowIn /
	NotShowIn strings exist before testing their contents.  Fixes
	https://bugzilla.novell.com/show_bug.cgi?id=177777; this was
	filtering all .desktop files!

* libnautilus-private/nautilus-directory-async.c
	(is_foreign_desktop_file): Split the contents of the OnlyShowIn
	key; it can be a list of strings.  Also consider the NotShowIn
	key.  Fixes https://bugzilla.novell.com/show_bug.cgi?id=176123

Skip .desktop files which are specific to other desktop
	environments ("OnlyShowIn=foo").  Fixes these bugs:
	http://bugzilla.gnome.org/show_bug.cgi?id=338933
	https://bugzilla.novell.com/show_bug.cgi?id=158158

* libnautilus-private/nautilus-directory-async.c
	(is_foreign_desktop_file): New helper function: returns TRUE if
	it gets a .desktop file with "OnlyShowIn=" not for GNOME.
	(directory_load_one): Use is_foreign_desktop_file(), and skip
	.desktop files which belong to other desktop environments.

* src/nautilus-application.c (remove_desktop_dot_hidden):
	Unlink ~/Desktop/.hidden, which was a Suse hack.
	(finish_startup): Call remove_desktop_dot_hidden().
