Some wolf house and wand tweaks

Also some random commented-out debug statements in WandItem. Something
went wrong there, but seems to be ok now. :\
Some fixes to messaging for heal/disarm and force.
Switch to Java 1.6 to get rid of an annoying build path warning on Mac OS.
Revert "Always overwrite Magic builtin schematics, to keep them updated."

Now that we have "clearcache" we don't need this.
Some minor wolf house updates.
Make stash directly show your ender chest inventory.
Allow generic "player" spell parameter to target a specific player.

This replace's Gather's player parameter. UndoSpell still has its own
for now, I didn't want to mess with it.
Some minor spell balancing and tweaks.
Some more targeting tweaks, add "block" target type to ignore entities.
