• Library: major refactor of the fdiff.diff module
• Library: add new public external_diff function to the fdiff.diff module
• Library: minor refactor of fdiff.color module (removed unnecessary import)

v0.5.1

• fdiff executable: Fix help message - added information about pre/post file argument support for URL in addition to local file paths
