Title: Revert rtvd to calculating 2 steps inside relaxing_tvd

This is a controversial change. Nevertheless I'd like to consider it.

Disadvantages:
- problems with external gravitational potential as it will certainly screw *outd* and such

Advantages:
- less communication
- lesser memory footprint
- make certain algorithms (FARGO I'm looking at you) easier
