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

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
    How does it look like:
