* scm/output-lib.scm: Rename guitar-tunings to guitar-tuning and
add tuning for 4-string bass and some common 4/5-string banjo tunings.
New function (four-string-banjo) turns a 5-string tuning into a 4-string
tuning.
New function (fret-number-tablature-format-banjo) computes correct fret
numbers on 5-string banjos.
* ly/engraver-init.ly: Default stringTunings = #guitar-tuning
Add beam correction to TabVoice.
* scm/define-grobs.scm: Adjust notehead offset. Print fret numbers
using bold font; makes tabs more readable.
