[gtkada] Documentation generation tool

Although probably usable, this tool is currently quite strongly linked to
GtkAda (for instance, it tries to document the signals, which no other toolkit
has).
This is probably a good starting point however if someone wants to improve on
it. Of course, getting an Ada version would be even nicer :-)
