Mozart KV545: Various fixes (Andrew Mansour)

Bar 36: gis->g, f->f!
Bar 53: octavation error
Bar 68: missing rest on first beat
Make BWG088 corrections as requested by @dominicus

I don't know anything about this piece so I can't vouch that the changes are
correct, but I thought I would create a pull request. In accordance with issue

I checked these against the Open Goldberg Variations edition. The first
correction would make us match their edition, the second correction would make
us diverge from their edition.
Make small fixes to Ich Grolle Nicht

Make optional notes have small notes heads, and fix spacing in the last
measure.
Fix mutopiatitle to match piece name
Fix partial warning in Sonate 2, 3, & 4
