Undo support

[shaiay]

Hi

After some frustrating silly deaths I decided to add an undo function. I takes you back 10 steps, and will also work when you're dead.
I know there is a small chance of it being acepted with it being against the whole roguelike idea, but just in case, I tried to make it as easy as posible to merge.

It works by saving the game/level on hero.idle() to a size 10 FIFO buffer which is written to using a ByteArrayStream.
When requesting undo the game & level are reaf back from the first (oldest) FIFO elemet.

I would certainly enjoy that feature. Many of my deaths are due to not paying enough attention, but often I don't really want to pay more attention.

Maybe if undo is used during a game, the game should not appear on the leaderboard.

Maybe, if is used...you lose the half of your money..and a randon number of
items.
