[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

Fixing percentage color while charging for "text only" style

Fixing percentage color for JB style

Adding green percents color when charging and >90% for circles with percents too

Including Juba's changes regarding battery tile with no battery in statusbar
and styles order

Line to long and use static reference

How does it look like:
