F2 text palette should use MScore1 for musical symbols (2.0 regression)

Steps to reproduce bug
1. Double click on text to begin text edit mode
2. Press F2 and insert a quarter note or flat sign

Expected behavior: quarter note or flat sign should approximately match size of the surrounding text

Actual behavior: the music symbols are far too small.

Discussion: It looks like the music symbols are based on the MScore font (used for staff notation) instead of the MScore1 font especially design to match with the surrounding text.
