Quite a bit I think. It involves changing the XML format. I suggest we
move this to 0.9.4 and add a function not_implemented_in_parallel that
we can put in some key places, like in parsing of MeshFunctions. Then
all demos that fail in parallel will give a sensible message about why
they are failing.

Bug description:
Reading MeshFunctions from file fails when running in parallel. Without a rewrite of the XMLMeshFunction, where the mapping between the mesh entities and and the vertices is stored as part of the file format, only vertex and cell valued mesh functions can be used in parallel. Hence, we only address the cases of cell and vertex entities for now.
