Fixed pathfinding: could still pass through pubs and free mines.
VisualPathMap now scrollable through the history.
Made TileInfo and PathMap cloneable.
sites in range list is now sorted by distance
Extended Board.java with a Tile comparation of taken mines and players
(regexp).
Hero now tries to get as many mines as possible, until he needs a drink.
The bot is working! Tweaking a lot by fighting in the arena and
analysing the battlefield. Currently added (re)capturing claimed mines
and player attack only with enough health. Reorganised the project
structure a bit.
