quick patch 1.0.2

while more substantial updates are being worked on, this update patches two egregious typos that made certain abilities work very differently from intended:

• vanguard's Vigilant Defender perk was supposed to be 1/Battle. it wasn't, allowing a player to infinitely use powerful vanguard abilities at no action cost
• the Bugbear Crusher has an attack that was supposed to have 2sq reach; it had 10sq, probably because i mixed up my numbers and accidentally used the "5ft per square" notation games like D&D and Pathfinder use.

these are both now fixed.
