[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] #5215 make metronomeMarkFormatter more flexible

[Auto mailings of changes to Lily Issues via Testlilyissues-auto]

Here is the nearest I can get to Kieren’s suggestion (https://codereview.appspot.com/327620043#msg21). This is far from optimal: Currently, it works only easy with grob properties of MetronomeMark (see line 54ff.), not with context and event properties. But it looks as if it works (line 75ff.).

Disclaimer: I don’t exactly know what I’m doing here. F. e. I have no idea why the props argument knows about the grob in line 8. I copied that from Harm’s proposal at https://sourceforge.net/p/testlilyissues/issues/5215/#e472.

make metronomeMarkFormatter more flexible

This adds the context properties tempoEquationText, tempoBetweenText and
tempoShowParentheses as shown in http://lsr.di.unimi.it/LSR/Item?id=1008

It also allows to scale the size of the notes in a metronome mark
independently from or rather relatively to the text and numbers.
I added this possibility because http://lsr.di.unimi.it/LSR/Item?id=1008
suggests smaller note sizes; so there seems to be a need for that.

The default values are chosen so that the whole thing is backwards
compatible; to achieve this, tempoShowParentheses accepts not only
boolean values but also the symbol 'if-text.

I chose the name tempoShowParentheses instead of tempoHideParentheses
because this property also allows parenthesizing text-less
MetronomeMarks.

Contains regtests.
