New PKGBUILD for fusilli

Remove gcc from makedepends. gcc is a member of base-devel.
Add marco as optdepend.
Cleanup depends.
Use spaces for indentation.
Remove:
	--enable-dbus-glib: removed from fusilli.
	--disable-metacity: removed from fusilli.
	--disable-gnome: removed from fusilli.
	--disable-gnome-keybindings: removed from fusilli.

	--enable-glib, --enable-inotify, --enable-annotate, --enable-librsvg,
