Support setup phase in CECP protocol

I liked the feature offered by Fairy Max playing Musketeer Chess where a first window with the 10 pieces are showed first.

Fairy Max window that opens at the beginning of the game to chose the first fairy piece by white

And Following choice of the engine choice: Here i made of the choice of a Unicorn and the engine have chosen an Amazon.

After that the engine choses the second fairy piece and the following window appears where whe have to place his Unicorn as first fairy piece

Here is the final position which is very fine and then the game can begin.

I chose unicorn in g0 and engine chose unicorn on b9

Then i chose Amazon on c9 and engine chose amazon on f9
