Title: Improvements for Windows and JRuby support

This is partial fix for #44.
1. for both JRuby and Ruby on Windows FileSystem.path_parts() should be improved to drop "c:" (or whatever else) which corresponds to root ('/')
2. Also for JRuby we need to un-define several StringIO methods which are specific to JRuby.
