- refactor idletime/myidle/uptime/myuptime variables
- printk() goes into DEBUG section (will update Makefile later on)
- start work on LKM hiding (callbacks still missing)
- various smaller fixes and clearups for LKM hiding purpose
- we still cannot unhide after successful LKM hide, as we loose
  /sys/module interface (idea: add a simple /proc entry for that?)
- trivial strings update
