[glibmm] Gio: Add some TODOs about changing the base classes.

[Murray Cumming <murrayc src gnome org>]

commit c43ced750b04b8ae0556e8dfe317a4dbb6da327f
Author: Murray Cumming <murrayc murrayc com>
Date:   Tue Mar 26 10:45:38 2013 +0100

    Gio: Add some TODOs about changing the base classes.
    
        * gio/src/actionmap.hg
        * gio/src/pollableinputstream.hg
        * gio/src/pollableoutputstream.hg
        * gio/src/remoteactiongroup.hg:
        We should probably derive from their prerequisite
        (required) classes instead. These were added in
        glibmm 2.34.
