Version 1.0.0 beta

Finally a release, a few years too late. Should be fairly reliable, but all files are validated so you can be sure it is correct as long no error messages appear. The cgCompress file format is stable, changes will only be made if they are backwards compatible.
Included is a copy of imgviewer to display the produced cgCompress files without extracting them.

The Windows binaries are 64 bit only. Create a issue if it fails to load due to missing DLLs, I didn't have a clean system to test it on and my testing procedure might not be perfect.
