Going 1.0, adding image preview etc.

With the many new features lately like preview of images found in files, and support for detecting the presence and extraction of PNG, JPEG, bmp, bz2, swf, cab, avi, wav files in completely unknown uncompressed archive formats it had to be 1.0.
Support for DOOM and HalfLife archive formats was ported from the Delphi version as well.
