Add battery charge thresholds limit (#637)

* added battery files

* finished main battery script

* added battery_script in auto_cpufreq

* fix some errors with batterys

* setup some battery stat printing

* added battery config printing to monitor and live modes

* fix some bugs now works on daemon and monitor mode

* cleaned up battery.py

* started to fix writing issue

* still debuging fixes

* bug fixed thinkpad stop threshold cant do below 65

* updated auto-cpufreq.conf-example with battery thresholds
