Regexp filters

For some time I've used a combination of grunt plugins ("string-replace", "inlinelint" + "clean") for linting *.cshtml files that contain Razor syntax which is not kosher with jsHint.
Thought that it could be a good idea to add this as a functionality directly to inlinelint as I'm sure there are many other formats that does not conform well to inline linting.

I've added a cshtml-fixture and a test that specifically remove the occurrances of code that I've had issues with.
