Display .qm plurals

[dwaynebailey]

The qm parser can correctly parse plurals but Virtaal does not display them. We might have lost this functionality when we made .mo and friends rely on information in the file rather then the size of the multistring.

Newer .qm files have a NumerusRules section which we parse since r14908. I haven't deduced yet how this is used, I assume it provides a reference to to the numerus data that Qt maintains. We would most likely need to use these lists as we would need to in .ts files.

My simple hacking shows that we need to do the following:

• Add hasplural to qm.py - easy

  def hasplural(self): return len(self._target.strings) > 1

• Remove assumptions that unit.source is a multistring if we are a plural. See unitview.py and pogrep.py. I simply added isinstance(unit.source, multistring)

Allow Virtaal to display .qm plurals

An alternate idea would be to ensure that all .qm sources are multistrings, then we wouldn't need to test using isinstance.
