** Fixes part of bug #559371

2008-11-05  Matthew Barnes  <mbarnes@redhat.com>

	** Fixes part of bug #559371

	* composer/e-msg-composer.c (e_load_spell_languages):
	New function loads a list of GtkhtmlSpellLanguage structs from
	GConf, taking care of details like converting language codes to
	structs and ensuring the returned list is non-empty.

	* composer/e-msg-composer.c (e_save_spell_languages):
	New function saves a list of GtkhtmlSpellLanguage structs to
	GConf, taking care of details like converting the structs to
	language codes.

	* composer/e-msg-composer.c (msg_composer_constructor):
	* mail/em-composer-prefs.c (spell_language_save), (spell_setup):
	Simplify the logic by using e_load_spell_languages() and
	e_save_spell_languages().
