Don't warn when reading a .xml when we previously read the .ephy-extension

2005-11-18  Christian Persch  <chpe@cvs.gnome.org>

	* src/ephy-extensions-manager.c:

	Don't warn when reading a .xml when we previously read the
	.ephy-extension for this identifier. Allows .xml and .ephy-extension
	to co-exist in ~/.gnome2/epiphany/extensions.
