Jox_work

This version of jox works, plays leagal moves etc (as far as I tested), but
it has no move ordering implemented yet. Also, the idea concerning the figpos-array
was tried, but it seemed to be slower than before ! (no final evaluation, though !)

Next steps to be done (only the most urgent ones :-) ):

- implement move ordering

- start working on the database (consider the bwi-files !)

- interface to winboard
