EXPERIMENTAL: put a reminder of the mm rest on the last page at the top.

Introduces grob MultiMeasureRestReminder, controlled by
createMultiMeasureRestReminders.

TODO:
 * regtest
 * a nicer layout of the reminder (use a mmrest-like symbol?)
 * more structured positioning and extent routines for the grob.
 (the grob should be ignored for pure computations.)

Set page breaking properties in the System grob

* Record system rank within page in rank-on-page property

* Record page number in page-number property

lily/page-breaking: pass vector by reference


lily: fix some type conversion warnings


Document why System::rank_type is int16


Documentation: fix typo in German spacing.itely file


Documentation: fix typos in tool naming

There's some stuff here that I already spent time reviewing, and having to sift
through it to find the new stuff is asking a lot.  Would you mind narrowing this
review down to the code for the feature itself?

I'm not asking for anyone to review. It's context to the other change about
multi-measure-rests.

It's also a demonstration of why I want to get away from rietveld, because it
doesn't handle dependent changes.

OIC.  An MMR reminder sounds interesting.  Does the problem tie in with others
like repeating the current chord name after a page break?

I think you could build that in a similar fashion, yes.

abandoning; implemented as user defined reminder instead
