Globbing causes too large an argument list

[timwsuqld]

Trying to use globbing (so we can do ignores) causes the argument list to be too long to phpcs. Commit 933d01a seemed to make sense, but actually passing those options to phpcs is really useful to prevent exactly this issue. Please consider reverting the commit, then people have the option to do both globbing through Grunt or passing it to phpcs.

Bringing back the ignore and extensions options will solve this issue, as then we can pass directories in instead of lists of files
