First GUI version

This is the first version to feature a graphical user interface to make the software more accessible.

New histogram matching technique

The software now uses a new histogram matching technique which utilizes all three RGB channels. This should reduce color artifacts and allow for more accurate results in scenes with strong flickering.

In addition to that several annoyances regarding file handling have been fixed.

Initial release

This is the first somewhat usable version of this program. It might still fall apart if you do something unexpected.
