[1/2] frameworks: Adding old-school (JB like) battery percents style
due to its better visibility.

Also added "No battery" style.

Added percents visibility while charging and
colorizing percents while charging

One selector made obvious

Removing unnecessary code

Setting green color for text 90+% charged

Now bolt color means color of circle battery, not percents

How does it look like:
