Fix commas in regexp

[DannyBen]

This patch is intended to solve issue #2 that prevented regexps from having a comma or parentheses in them.

I had to do a small conceptual change: Instead of using explode to extract the comma delimited parameters, I am passing anything inside the parentheses directly to the rule handler, as a string.

Then, the few rules that do need several arguments, like in, between, property and method simply explode it themselves.

Hi @DannyBen, great work! Take a look of my new PR #6. This PR do the same stuff than your PR but with only one more line of code, and can be better than refactoring all rules that accepts more than one arguments.

Wow, that is a 5 years old open PR - sorry, don't remember a thing about it, and does not seem to be maintained.

I am closing this ghost PR.
