Merge branch 'bnnsc1.7.0' into 'master'

Misc 1.7.1

Change Notes:  
* Lower level of enemies in bandit fortress vault  
* Reduce the frequency at which rares take talents in the Combat Techniques tree, potentially alleviating a concern that rares have too high accuracy in 1.7  
* Minimize use of raw talent level where effective should be used and has precedent for use
