Allow to specify glob or regex in ignorePaths

[Zip753]

Hi, thanks for the awesome module!

I'd like to propose to add regex as an option for ignorePaths, so that it's possible to ignore, say, the whole subpath (directory in pages, respectively). Extension of #2 and #3

Thanks for the suggestion @Zip753 :) I've added this in v2.4
