This release does two parallell analysis of the file, one with strings in quotes (") and one without, and selects the best separator. Should solve some situations where it selects the wrong separator due to e.g. commas inside strings.
Still sucks at quoted quotes though :P
This release should also be able to handle larger files before getting an "OutOfMemoryException", but probably not by much (and it will take a long time to get there). It's half done.
