Installs an accelerator in this group, using an accelerator path to look up the appropriate key and modifiers (see add_entry).
When this is being activated in response to a call to
accel_groups_activate, closure will be invoked if the
accel_key and accel_mods from accel_groups_activate
match the key and modifiers for the path.
The signature used for the closure is that of AccelGroupActivate.
Note that accel_path string will be stored in a Quark. Therefore, if you pass a static string,
you can save some memory by interning it first with g_intern_static_string.
