...by turning chase_eig_id into a module variable

...together with Miriam Hinzen.

Also in this commit: Slight beautification of the configure script output for ChASE.

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

Cleanup and bugfixes are required.

...also in this commit: Replace multiple definitions of lmaxb by a single constant lmaxU_const.

Bugfixes, put swapped some variables between hybrid/hybdat datatype, moved files from xc-pot to hybrid

Now fleur.F90 calls a subroutine that does most of the hybrid stuff.
In eigen.F90 only the non-local potential is added to the Hamiltonian

Removed most of CPP_INVERSION

Introduced module types_rcmat with a general type for real/complex matrices
Introduced general IO for these matrices

The problem is that this array has size 2 and in hsmt_nonsph the maximum
value of this array is used for some array allocation. If the system under
investigation only has a single spin the 2nd value is undefined.
