Fixed bug parsing file attributes on unix/linux file systems (dates and links).
Added new checksum method to the File class that can be used to perform cyclic redundancy check (CRC).
Updated the getPath() and toString() methods in the File and Directory classes to return absolute paths instead of a canonical path. This change will only affect symbolic links on unix/linux file systems.

This significantly improves the speed with which file attributes can be accessed on windows file systems, especially when accessing files across a network. Initial tests yielded over 3x performance enhancement.
Bug fix parsing extended file attributes on Windows. Found out the hard way that java.text.SimpleDateFormat is not thread safe.
