ictk - v0.1.1 Released (bugfixes)

This is a bug-fix release. A few changes in the PGNReader allow
it to be a little more flexible in handling different interpretations
of the PGN spec. Also there were a few bugs spotted in the chess model
when rare board positions were reached (like pawn checking the King taken
enpassant on the next move).

The next non-bugfix release will include the FICS interface.
