[pyclutter/wip/introspection] Add overrides for Animator.set_key() and State.set_key()

[Bastian Winkler <bwinkler src gnome org>]

commit 6bcdda7050303ff7257f03c20d76a549a61a7749
Author: Bastian Winkler <buz netbuz org>
Date:   Sat Nov 12 18:03:27 2011 +0100

    Add overrides for Animator.set_key() and State.set_key()
    
    This is done by putting some specific values in a GValue container to
    make sure to pass to correct value type.
