1) Fixes for suspend/resume (improved it for iPAQ, shouldn't have changed

   anything for Z) -- It seems that this also fixes the 70% CPU load
   problem (needs more testing/feedback though)

2) the launcher now creates a /var/run/opie.pid file containing its pid

3) the launcher catches SIGTERM and kills all its child processes
