20	player.dat upgrade	epyon	epyon	"player.dat needs to be redesigned broken (see PlayerDat). Please link this task to all player.dat breaking tasks. Things to think about:

 * Achievements
 * Unlockables
 * Ghosts
 * Unique Items (gallery?)
 * arbitrary amount of monsters/items
 * arbitrary amount of challenges
 * custom challenges/levels, etc
 * version compatibility

The format should be flexible to allow varying amount of data.
Current idea is to implement and use TLV from VTicket:#27, to allow adding data without breaking the format. Also remember to check the format against the planned weapon type refactoring."	task	closed	blocker	0.9.9	engine	0.9.8.10	fixed				21, 22, 23, 24, 29, 63
