allow begining of piece move/drag before opponent moves

[GoogleCodeExporter]

You should be able to start moving your piece before your opponent moves
his piece. I guess it's illegal in OTB chess but all the other chess
programs do it so it's hard to place fast time controls competitively
without being able to do it.

Isn't this the same as issue 271 ?

No. Premove is when you make a complete move (drag and drop the piece on a 
square)
before your opponent makes his move so that when his move is made, your chess 
client
makes the move on your behalf automatically.

What I'm talking about is the ability to start dragging a piece -- but not drop 
it --
before your opponent makes his move. This apparently isn't possible yet with the
pychess board code.

If premove was implemented, this would follow automatically.

Some would suggest that this is less cheating according to chess rules, but as 
I see
it, touching a piece while you are not to more, is just as much cheat as 
putting it down.

However this is really easy to implement, only changing BoardControl.py, so 
while
premove might take a few releases yet, this could potentially be in the first 
Stauton
alphas.

I've got this working for the most part in the attached patch. The only 
remaining
small issue with the patch is when you pre-drag and hover over a square with 
your own
piece on it, wait for the opponent to capture there, and then, during the 
opponent's
capture animation, you quickly drop your piece on the square to capture his 
piece in
turn, an animation back to your pre-dragged piece's source square is run before 
the
capture.

The patch also fixes issue 483.
