new pandemic release

games::pandemic 0.7.0 is now on cpan, with a lot of improvements and a crash fix:

• wiping all cubes from a city if a cure has been found for the disease
• reacting to winning conditions
• reacting to game over condition when no more disease cubes
• possibility to see cards already played / discarded
• possibility to see past infections

i'm taking my time, but all in all there is progress... :-)
