Version 1.0 beta3 (bugfix)

Changelog:

- changed back canceling of dbs work to syncron instead of asyncron in dbs_timer_exit function to avoid random kernel chrashes (again oops in smp.c)
  when using this governor with the cpufreq implementation of kernel versions 3.10+. problem was initiated by governor restarts during hotplugging
- as an additional precaution check if a core is online before doing critical stuff in dbs_check_cpu main function (might be removeable at a later
  time, more analyses/tests will show)

profile header file (Version 0.3 beta2 OPO)

- corrected/adjusted sampling rate values in settings where they were lower than the minimal possible value of 60000
