Subject: Move mime-type functions from document-facrory to file-helpers so that it

2008-11-29  Carlos Garcia Campos  <carlosgc@gnome.org>

	* libdocument/ev-document-factory.c: (get_document_from_uri),
	(ev_document_factory_get_document):
	* libdocument/ev-file-helpers.[ch]: (get_mime_type_from_uri),
	(get_mime_type_from_data), (ev_file_get_mime_type):

	Move mime-type functions from document-facrory to file-helpers so
	that it can be reused.
