We've right (in fact I began the refactoring at 5 in the morning I was
a bit tired :D),
and I am merging everything.  In the train this morning I've added
accel supports
in the commands :

 each tools has a path:

  ^ '<VisualGST>'

and we use the command class name to generate the full path name

for example   '<VisualGST>/OpenBrowserCommand'

It seems fine for me

Yep that will be cool

For the header you could do like a lot of IDE a allow the user to choose
the header: we could encode the licences (Mit, BSD, GPL, ...) or anything
else ...
