Added EosCustomContainer C class for gjs containers

forall cannot be overridden in gjs. There's an upstream bug here
https://bugzilla.gnome.org/show_bug.cgi?id=701567
but that does not look like it will be fixed soon. So for now
added a small c class that take care of GtkContainers add, remove
and forall methods. This makes it possible to write generic containers
in gjs. See docs for an example
[endlessm/eos-sdk#481]
