Removed jij data-type, added first implementation of further force-theorem modes, these lack tests&support in xml-shema

Fixes to make pbe faster (again after refactoring of xcpot) Changes for reanabling old CPP_66 functionality

(The bugs were somehow introduced due to the inclusion of the hybrid code.)

This broadcast was missing for the use of this variable in vgen/vmtxcg.F90, line 292

This might have caused an error in mpi parallel mode.

This might have produced real bugs in mpi parallel mode.

This is not yet tested.

Also in this commit: Small syntax correction in mpi/mpi_bc_all.F90.

removed: weight, natd, nkpts,nkptd

- made l_zref a local variable no longer in type sym
- changed the setup of the parallelization (mpi/mpimakegroups is obsolete)
- added new command line switches yet to be documented :-)

The wrong data types lead to some arrays being overwritten and as
a consequence the error map2 was caused in vacfun if the xml code
path and parallelization was used.

...still not functional.

Tests added: CuBandXML, CuDOSXML.

CuDOSXML does not yet pass.
