Release notes for GNU Solfege 3.21

Solfege 3.21.3 not out yet

solfege.dev revno 2079

mpd: try to avoid crashing noteheads when displaying two noteheads at the same step, but with different accidentals.
140% line-height in the generated user manual
We can now place exercise modules written in Python in ~/.solfege/exercises/dirname/modules/
the elembuilder module changed how it stored its statistics. So all elembuilder statistics will be lost. We will save a backup of the statistics database the first time 3.21.2 is run.
the statistics page for each exercise now have a button that let us delete the statistics for the exercise.
The --debug option will also show the module name as a tooltip for the link button that starts the exercise.
Make the "Guess answer" button be sensitive only when the user have entered an answer.
Statistics viewer: added a row to the percentages table showing count and percentage correct for all questions asked in the session, day, week and all-time.

solfege.dev revno 2054

added import and rimport statement
add INSTALLDIR/exercises/standard/lesson-files to the include() functions search path
dataparser will parse to a parsetree that we interpret.
remove all support for file formats that depent on lesson_id. Did not remove the lesson_id variable from lesson files since this would reset the statistics.
rhythmtapping and rhythmtapping2: rest handling bugfix
fix bug #237
HarmonicProgressionLabel: set_alignment bugfix.
The frontpage will show the filename if the app is started with the --debug command line option.
idtone exercise: show statistics when the user configure the module himself. And remember the config.
SolfegeApp: don't sync the statistics database until the last exercise is shut down.
compareintervals: fix "Repeat first" and "Repeat last" sensitivity
gu.FlashBar: display extra strings (set by kwargs) in the same font as the rest of the string.
Put a deprecation notice in the chord modules gui.
