* eggaccelerators.c: (egg_accelerator_parse_virtual),
(egg_virtual_accelerator_name), (egg_virtual_accelerator_label),
(egg_keymap_resolve_virtual_modifiers),
(egg_keymap_virtualize_modifiers), (reload_modmap),
(egg_keymap_get_modmap):
* eggaccelerators.h: fix mismatched modifier mapping between egg
and GTK (so that e.g. <Super> works) and replace some custom
functionality with stock GTK
