[pygobject] Add GIBaseInfo.equal method

[Simon Feltman <sfeltman src gnome org>]

commit c86b2fe8d01070f06c45fffd910d890afba1313a
Author: Simon Feltman <sfeltman src gnome org>
Date:   Fri Oct 4 13:41:08 2013 -0700

    Add GIBaseInfo.equal method
    
    Break PyGIBaseInfo rich compare into two methods: equal and richcompare.
    Equal is a direct exposure of the GI method and richcompare makes use of
    this with additional support for Pyton "==" and "!=" operators.
