Leading and/or trailing spaces in URLs are breaking the crawler

Created by: ZaiLynch

I'm not sure how URLs with leading or trailing spaces end up in the crawler, though once they occur, they're triggering the rescue in lib/arachni/uri.rb, in the definition for self.parse( url ) I guess that a url.strip! should solve this, though I'm not certain if the root cause for leading/trailing spaces might also break something else.

This occurred on a nightly build from about 2 weeks ago.
