Implementation of 6th order dissipation operator compatible with the 6-5

finite difference operators. Not fully tested yet. The MoL dissipation
interface was shamelessly stolen from Eriks Dissipation thorn (in AEIThorns).

Things to do:

Add a test for the presence of MoLQueryEvolvedRHS (since the use of
dissipation is optional, I didn't want to require the presence of
this routine).

Add compatible dissipation operators to the other finite difference operators.

More testing.
