- Moved the card collection out of the GameApp class to clean up the dependencies

- Added method to build a card collection independently of the GUI to ease my unitary test application
- Added part of some network GUI I'm working on, it's #ifdef out, I'm only committing this part to ease later merges
- Added the beginning of a serialization code of the Player and related classes used for network support
- various other minor cleanup
