Subject: GRHydro: Added parameter to perform sync on conserved quantities
 only.

Primitives are only sync'ed after regridding to get initial guesses.
Schedule Primitive boundary call in PostRegridInitial if sync_only_coserved == yes.

Fixed issue with the sync call in CCTK_EVOL after MoL_Evolution when sync_conserved_only==yes:
Conserved vars must be synced here as well, otherwise conserved vars are reset to atmospshere whereas
primitives are not! This is wrong.

Patches by Christian Reisswig.
