This is a simple patch that revamps (mostly dramatic buffs) Finishers since its a simple area to improve and I'm tired of hearing people suggesting that you just not use finishers.  The general theme of the changes is that Brawler damage is heavily based on multihits (biggest proc emphasis of any class) and so single hit finishers need to have BIG numbers.  I have tested a lot of damage formula variants and this is likely too conservative.

These may not be perfect, but I am 100% sure they're a vast improvement over the current tree.  Worst case is the class manages to pull off half the damage of Arcane Blade/Marauder or something :p.

Aside from that I made a few simple quality of life improvements.

I tried to be thorough with tooltip updates and other little things but I'm often bad at that, I may have missed something!

DETAILS:
- Added 1 rank of Unarmed Mastery baseline because the early game is ridiculous without it on both normal (!) and Nightmare.  You run from snakes.  Its not pretty.

- Improved Concussive Fist's numbers a bit.  Not very happy with this but I wanted to keep this as simple as possible for now.

- Deleted Body Shot

- New Talent:  Butterfly Kick.  Low damage Giant Leap.  Huge mobility gap fix thats dependent on CP, really fun in testing and encourages smart use of CP.

- Vastly improved Haymaker damage.  I tried a lot of damage models with this, originally determining it needed to be something like 800% weapon damage before it was really satisfying. Putting talent scale that high made it too strong at low CP so I changed the combo point scaling to multiplicative and doubled it.

- +2 base range on Spinning Fist because its much more fun to be able to use this as a primary gap closer instead of rush.  More CP interaction.
