Added new application "mobile" to layer23.

Added new application "mobile" to layer23.

This is the current status of the layer 3 protocols. Everything compiles,
radio ressource layer is partly complete. Everything is untested, so don't
expect that it runs and does something usefull. The next step for me is
running and debugging it.

Here is the list of files that are added / modified:
