JCZ 3.1 Enhancement Requests

[farin]

right click on board still change action / rotate tile

current impl impl is
rotate: basic feature (no animation etc), key /
fake middle button - I added feature - right click + shift - simulate middle click -> move board
(i think it is not key feature, there are anotjer possibilities to move board - ASWD and dragging board with mouse)

i don't want to make big chaneges, 3.1.1 should be about bugfixes ("2-tiles" bug, phantom on abbey) and mainly hotfix
to add private game - which is last feature to add. Probably secure game with password, it's much easier to implment and to change UI then invitation model (which i personally like
and I will try add it too in future)
