- duplicate code into shared method - removed useless isQuote() Method. Logic for quote is in main loop.
…open quotes This breaks the API by extending the interface ArgumentCompleter.ArgumentDelimiter Not sure whether this is still acceptable for jline2 2.x
- provide option to complete folders themselves - provide option to not complete files - allow suppressing final blank (fix #90)

This supercedes #203.
This fixes #90, and adds a lot of tests and some features to FileNameCompleter and ArgumentCompleter.
ArgumentCompleter will now attempt escape candidates based on the ArgumentDelimiter. This should help e.g. with Filenames having blanks. If the argument is within the context of an opening quote, no escaping will happen, but the argumentHandler will provide a closing quote if the subcompleter suggests a candidate ending with a delimiter (blank).
FileNameCompleter can now configured to not provide a blank, it can be configured to complete folders themselves and also to not complete files (just folders if that is enabled), and users can add a filter in subclasses to exclude files based on custom logic.
I did not test the changes on other operating systems than Linux.
The small commits fixing minor stuff could be merged early, if you like.
