Log:
Add optional module that compiles with gtkmm, i.e. in C++.

This was just a crazy idea, but it turns out to be extremely easy.
This can be used as a place for new GUI elements which people prefer
to write in gtkmm/C++ instead of C. It's disabled by default.
Use configure --enable-gtkmm to enable it.
