fix brevis rest display (2B, 3B...)

In a context of modus perfectus, the longa rest should by default take 3 interlines. With dur="2B", it should take two interlines.

Thanks! In the context of the Vitry project, would it be possible to always encode longa/brevis rests as 2B or 3B? (in the MEI output file). In fact verovio is structured in a way that makes it almost context-blind, so for instance you don't really know the modus of a specific passage that would give the key for interpreting ...

Done... In fact , it only concerns "longa" rests (graphically, "brevis" rests take all one interline, regardless of their duration, and the value "1B" is not defined in MEI !)

In the last commit, here is how mensural rests are interpreted:

• "longa" -> 3-space rest
• "3B" -> 3-space rest
• "2B" -> 2-space rest
• "brevis" -> 1-space rest (no matter the modus...) Are we happy with this..?

It's fine like this, thank you ! Last commit now on polenord.ch. Coloration of longa rests definitively disabled.
