xpy 0.8

Being in development for more than two months, the new xpy changed a lot. Besides many changes under the surface (e.g. commandline switches), new features were added and multiple bugs could be fixed.

A lot of more features will be added until 0.9, mostly to speed-up Windows, but also to increase usability.

Once all features are implemented (within 0.9), smaller release-steps might follow, until the software is 1.0-ready.
