Save/Load hero

Basically, at the beginning of the game you can tell the old wise man
your name. If you return later to the game and use the same name again,
you will reload your previous save data. (Stats/Xp/Items, etc)
All the data is saved realtime.

Resting aint safe no more!

You can get attacked by enemies while trying to rest (1/8th chance right
now). You will be forced into the combat state, so running away also has
risks. Monsters will remain in the room aswell!
