Dir.glob now ignores files that don't need to be watched

Browse Source 
By default, we don't watch ., .., .bundle, .git (this is HUGE), log, tmp and vendor (this is also HUGE). Also don't append '/' to the dir given to Guard::Listener#potentially_modified_files, the method now handles it internally.

In my case, Guard::Listener#potentially_modified_files was taking ~56 seconds (in a big Rails project), it takes now... less than 1 second.

Enjoy.
