Whole-measure rests throw off note spacing in other staves #23

In certain measures, notes are severely misplaced, often entering the following measure. This seems to be caused by the presence of an <mRest> element in another voice. A dramatic example of this bug can be found at DC0302. A simple example is in DC0212. Both paginated and scrolling canvases have the issue.

Wrong time signature in the mei can cause this behaviour: 2/2 isn't the correct time signature for this piece, it should be 4/2.

Right. I've added a function to MEIMassage that replaces all 4/2 time signatures with 2/2 signatures (retaining the "cut time" symbol). It's untested (my libmei installation is not working) but it is a simple enough function. We will use it on our next export and massage. You may need to incorporate it into the scripts.
