LEFT_BOARD_OFFSET

fixed some bugs:

* most notably, all levels now have a portal when generated (I THINK THIS IS TRUE -- LET ME KNOW IF NOT)

* also, clicking to cast spells always works (previously, it didn't work when casting spells more than 1-2 squares to the right of harold

* also tweaked the hallway generation so that they're a bit wider

* also, it's now possible to fight and defeat the wizard glumgraymore -- previously the game would ERRONEOUSLY claim that "You have defeated the wizard glumgraymore and retrieved the treasure" when harold reached dungeon level 10 -- just after the third boss fight! in light of this, i've reset the high score board.

* best of luck!
