gtkmm documentation issues

["Jonathon Jongsma" <jonathon jongsma gmail com>]

It appears that there are some issues with the documentation on
gtkmm.org.  Some pages seem to be missing (or the links are
incorrect?).  For example:
http://gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGlib_1_1SignalProxy0.html
(when I clicked the type name on this function:
http://gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1Button.html#515244a851fd9874cc481cdfc5ebf512)

There also seem to be issues with the sigc++ documentation as well.
If you go to the sigc++ reference documentation and click the link
that says "sigc::functor", you end up at this page:
http://libsigc.sourceforge.net/libsigc2/docs/reference/html/namespacesigc_1_1functor.html
which results in a 404 error.
