Linux Server 0.6.3 released

Fritzle has written a new version of the Linux server.
I didn't test it but I trust him ;-)
Changes:
- The program has been split up into many source files.
- An init-script has been added. The script was made for
Debian 3.0 but it should work with any other distro, too.
- PThread code was removed completely.
- Command-Line arguments were added. I also tried out some
code on config-files but it proofed to be not stable
enough to go into mainstream capifwd.
- A problem with zombies beeing created by handlers was
removed by adding a SIGCHLD handler.
- New "chackdep.sh"-script that checks for libcapi.
- The Code was cleaned up everywhere.
