support for passing the filename of default resource file on thecommandline

[Vlad Harchev <hvv hippo ru>]

 Hi, 

 Seems this is not the proper place to post wishitems on gtk, but anyway (just
want gtk developer notice this before gtk-1.4) - wouldn't it be nice if
yet another commandline switch accepted by gtk_init existed (like
--gtkrc=FILE) that specifies the gtk rc file (aka "theme") to be loaded
instead of default?

 Best regards,
