Subject: Reduced the messagetreeparser to aproximately what we actually
 require

While in a much more managable state it's still not pretty.
However, further refactoring can now gradually happen as we need to do
further work on it.

Things that should happen eventually:
* Simplify the logic that creates the messageparts (we don't need the  whole formatter plugin complexity)
* Get rid of the nodehelper (let the parts hold the necessary data)
* Get rid of partmetadata (let the part handleit)
