Tuanble Strings & Expandable Fretboard with Dynamic Staff Sizing

Users can now set how individual strings are tuned on the fretboard, as changing the tuning is required for some pieces on the guitar.

Additionally, players can now choose how many frets they are comfortable using - the staff resizes (more/less staff lines) so that the entire fretboard can be utilised without cluttering the screen with notes you cannot play at the selected fret count.
