Enabled PUGH to synchronize groups of arrays in one communication call

rather than doing it sequentially on individual arrays.
Nothing changes for the CCTK routines overloaded by PUGH.

For BAM and other thorns which don't care about groups there is now
a separate interface to synchronize individual arrays.

Also eliminated the restriction to synchronize 1D and 3D arrays only
- now it should do arbitrary dims (not yet tested).
