Added regex support to global filters to help combat fakes

I put in a rule for global filters that lets required & ignored filters contain regexs if the start and end with / 
I tested it and its working for my build .. I didnt add any documentation nor did i add support for categories .. the pull request is for the latest as of today .. im new to github collab so let me know if i did something wrong :)
I have a regex that seems to work pretty good with the current fakes that are being released .. Let me know if you want a copy.

I messed up my last pull request so this is another attempt at it
