pandemic turns implemented

so games::pandemic 0.5.0 is now released^[0].

the basic game play is now done: besides the player actions, the cards are now dealt and infections propagated. card limit is also implemented, so player can discard them if needed. add to that a bit of ui polishing, and we now have a solid basis on which to build upon...

next releases will see (in no special order):

• the special cards (including the epidemics)
• end of game conditions (both game-over and win cases)
• more ui polishing (i think the players cards will have their own toplevel)
• easier game play (drag-n-drop on the canvas)
• missing player features (dispatcher, medic)
• missing rule implementation (disease eradication, ...)
• start game dialog
• etc.

yup, that's still a lot to do, so expect other 0.x versions! ;-)

[0] and without any more warnings, since i spotted a bug in moosex::semiaffordanceaccessor which has been swiftly fixed!
