Fix bug 6824 - Mozilla component charset encodings are not translated.

	* components/mozilla/Makefile.am:
	Add new encoding tables sources.  Add GNOMELOCALEDIR define to
	make gettext happy.
	* components/mozilla/main.c: (main):
	Add gettext binding setup.

	* components/mozilla/nautilus-mozilla-content-view.c:
	(mozilla_view_create_charset_encoding_submenu):
	Use the translated strings for menu labels.

	* components/mozilla/nautilus-mozilla-embed-extensions.h:
	* components/mozilla/nautilus-mozilla-embed-extensions.cpp:
	Simplified by using an stl vector instead of a GList.  Moved the
	encoding tables to their own place.   Added functions for
	obtaining the encoding titles and encoding groups as translated
	strings.

	* components/mozilla/nautilus-mozilla-encoding-tables.h:
	* components/mozilla/nautilus-mozilla-encoding-tables.c:
	Moved the encoding tables to their own place.
