New Feature: Support for "KernelVariables": SYSFS like filesystem efficiently exporting arbitrary variables from kernel space (currently only RO)
- Bugfixes for race conditions and memory management bugs
   -> This version seams to be very stable for now. Ran multiple tests, in field system is now running 5 days with 8 tasks and 15 rt threads with periods between 1ms - 500 ms doing I/O as well as aperiodic threads doing network (TCP/IP, UDP transfer).
        Highest task entry latency measured 7 us (further investigations ongoing to drop this to 2 us) on BeagleBoardXM with 600 mhz
- moved some architecture indepenent classes to shared arch directory
- FAT file deletion support (beware: still experimental)
- thread arrival time now given as absolute 64 bit cycle time!
- telnet server enhanced:
   - support for ps, ls -lh and df commands using the sysfs (kernelvariable) architecture
