First untested draft of the repositories for "Jessie"

The three repositories jessie-experimental, jessie-own and debian-common contains the first packages. The files were built without errors and I have installed them manually in my virtual machine without trouble.

The repositories and the update process are still untested! So don't use them until I've investigated the whole process with a real installation.

Some of the packages were updated too. Just have a look at the packages lists in the repository overview.

Have fun.
