Title: BatteryGraphActivity: use shortHistory instead of m_histList

ArrayList shortHistory is a subset of m_histList which does not contain
points with the same battery level value. This serves two purposes:
- improve performance
- remove stairs in case when device was in the sleep mode for a long time
(Android logs an old value when he resumes from sleep, so if device was
asleep for 36 hours, after resume battery level will be looged the same as
before and then immediately next value.)
