add support for group of patterns

[efolio]

Hi,

I just thought that group of patterns would be cool, so I implemented them :D This is needed if you want to negate part of glob results and keep good performances. This is also useful to easily merge glob patterns together. You just have to put them in an array and it just works without one modifying the results of the others.

Hope you like it!

PS: why not bump to 1.0.0 after merging this? It seems that globule is rather stable now…
