Fix alpha bug, promotion bug, highlighting and move printing bugs
Two crippling bugs fixed: alpha was not reset at the start of later
iterations, and promotions were added to the move-list of deeper nodes
due to spoiling of the global nonCapts.
Essential deferrals were not correctly flagged on input moves.
Printing move lists could miss some initial moves, wrecking highlighting.

Add time control
A simple time control, finishing iterations, is added. Also a node counter.

More developed version for WinBoard Alien Edition
This commit contains the code as it was further developed on Windows,
and tested under WB-Alien. Highlighting was added, and a 3-ply fixed-depth
search is invoked when it is the engines turn to move. Piece-square tables
have been added to draw pieces to the center, and the move generator respects
the special Lion-capture and promotion rules of Chu Shogi. Most of the time
things work, but there must be a bad bug, as sometimes it suddenly moves
with an opponent piece!

Initial commit of Linux code
This embrionic code was developed on Linux. The move generator is
sort of working, but the multi-move feature is barely tested, because
the standard XBoard does not support that.
