Added Functions

Added the stance_set() function that allows setting combat stances.  It is currently broken.
Working stance set

stance_set() is working now.  Will need to look at passing value out to combat loop.
Update weighteffect.py
The Stance setting functions work.

Figured out how to pull variables from one function into another and push them back out. The result is a working stance setting function.
Added an initiative roller.
Aggressive updates

Built the core of the combat loop to include the player_attack, and monster_attack functions.  This was a pretty aggressive piece of code and it has a few bugs.  I left some troubleshooting lines of code in the combat loop and the other functions in order to allow continued troubleshooting by any parties interested.
