Added a new class to handle the pseudo-buttons on the canvas.

Browse source 
Added a new class, named Button, that has a clicked() signal,
and can be connected to the view to emulate buttons. While
I know that Qt supports widgets on canvas - I think it's too
nineties to have such square controls on something that can have
rounded borders.
