[gstreamermm] TagList: Corrected the constness of the internal tag strings array.

[José Alburquerque <jaalburqu src gnome org>]

commit fa915c1419f1f19393fbeb98a5b4b6c4c7f9ddf1
Author: José Alburquerque <jaalburqu svn gnome org>
Date:   Wed Sep 30 02:26:42 2009 -0400

    	TagList: Corrected the constness of the internal tag strings array.
    
    	* gstreamer/src/taglist.ccg:
    	* gstreamer/src/taglist.hg (_tag_strings):  Corrected constness,
    	completing a TODO.  I hope that's correct as my constness reasoning is
    	a little rusty.  Also added a comment as to why the array is 'extern'
    	in scope.
