Version 0.9 beta3

Changelog:

merged some changes originated by ffolkes (all credits and thx to him)
(source https://github.com/ffolkes/android_kernel_samsung_smdk4412/commits/534ec13388175eb77def021e92b0a44e1e3190d5/drivers/cpufreq/cpufreq_zzmoove.c

- reordered sysfs attributes
  description by ffolkes: some apps set tuneables by the order in which they are listed in the filesystem. this causes problems when one tuneable
  needs another set first in order to correctly validate. (e.g. you cannot set down_threshold properly until you have first set up_threshold)
- added 'fast down' functionality (based on commits to pegasusq in perseus by andreilux and extended for this version by ZaneZam)
  description by ffolkes: fastdown dynamically applies a (presumably) higher up_threshold and down_threshold after a frequency threshold has been
  reached. the goal is to encourage less time spent on the highest frequencies
- added 'hotplug engage' functionality
  description by ffolkes: when set >0, will not bring any cores online until this frequency is met or exceeded
  goal: reduce unnecessary cores online at low loads
- added 'scaling responsiveness' functioniality
  description by ffolkes: similar to 'frequency for responsiveness' in other governors
  defines a frequency below which we use a different up_threshold to help eliminate lag when starting tasks
- instead of failing when set too high in down_threshold tuneables set the value to the highest it can safely go
- increased possible sampling rate sleep multiplier value to a max of 8 (ZaneZam)
- added missing error handling to some tuneables (ZaneZam)
- fixed non setting of 'hotplug_sleep' tuneable when applying profiles (ZaneZam)
- added up/down threshold to debug tuneable (ZaneZam)
- some code style and comment changes/fixes (ZaneZam)

profile header file (Version 0.2 beta2):

- added values for following new tuneables (credits to ffolkes):
  hotplug_engage_freq (disabled by default in all profiles)
  scaling_fastdown_freq (disabled by default in all profiles)
  scaling_fastdown_up_threshold (default to 95 in all profiles)
  scaling_fastdown_down_threshold (default to 90 in all profiles)
  scaling_responsiveness_freq (disabled by default in all profiles)
  scaling_responsiveness_up_threshold (default to 30 in all profiles)
- adjusted up/down thresholds for core 2 in moderate setting
- changed sampling rate sleep multiplier from 4 to 6 in all settings (except in default setting)
