Enchantable Gloves & Misc Updates

Adds enchantable gloves, telekinesis gloves, fixes ice cream vat, allows area spells to be cast only on a targetted square at melee range (through items) for less charge depletion.  Adds a wizard "manual" in the wizard sanctum.

Changes what happens when you bump into another mob; this should prevent either mob from going somewhere it cannot go.

Makes gas masks work on choking clouds of smoke like they're supposed to.

Fixes a couple compile errors from combat+ due to different pathing defines
