emacs 24.4

Update to latest stable release, remove obsolete patches, remove devel version, remove outdated Japanese patch (pending update from [MacEmacs JP](http://sourceforge.jp/projects/macemacsjp/)), use HTTPS on homepage and mirror, change single quotes to double.
Presumably ``` depends_on "glib" => :optional ``` should now be moved to the global ``` depends_on ``` list if it was in the devel build previously, which is now the stable build?
