Do not use iNotify for detecting files

[lemonjesus]

iNotify is cool, but it isn't stable. At the suggestion of several people, I'm replacing iNotify with a different method for file detection.

Could you also have it sort the files by name for each group of files that is enqueued?

I guess - makes more sense than taking the diff and enqueuing it in any ol' order.
