Added $global indexical and fixed VS complaints

Project compiled fine with the test tools under unity, but VS issued
warnings.
Fixed ReSharper inspection issues

ReSharper consistently complains about acronyms in identifiers and
offers to allow you to add them to the dictionary, but then keeps
forgetting the dictionary entries, perhaps because Unity or UnityVS is
rebuilding the files containing them.  So I finally gave up and
disabled each individual line.  I also exempted the Unity Testing Tools
from inspection since the inspector finds billions of problems with
them.
