Cleanup and font rendering improvements

Some code cleanups and font rendering improvements, also added flat/sharps button for both, Pentanizer and Scaler app.

Pentanizer

Pentanizer different look at pentatonic shapes.

Basic idea is to use one shape, starting at root note, shape has following pattern:
3-2-2-2-3 where the last shape has an offset of -1
pentatonic minor scale, diagram, shapes with intervals
The only thing to remember is that, all shapes that are located bellow 3th string , needs to have an offset of +1. Few examples:
pentatonic minor scale, diagram, shapes with intervals
pentatonic minor scale, diagram, shapes with intervals
Once you can find root notes easily, I think this pattern method is better than five-shape pattern displayed in Scaler
