Also slightly cleaned up test NiO_ldau.

...still not functional.

Note: This is not yet functional.
      Also the test Fe_bct_LOXML is not yet complete.

Tests added: CuBandXML, CuDOSXML.

CuDOSXML does not yet pass.

Note: The XML output is not yet tested with this test.

The initialization was missing if no film calculation
was performed. I don't know why this variable is needed
in this case anyway. Hope the fix always works.

Now all ctest tests work on my machine.

The problem only occured because stars%gamx is changed after it
is initialized. I therefore introduced an additional variable
gmaxInit in type t_stars.

Note: There are still bugs in this part of the code.

Changed behaviour of strho switch. It is now only controlling if FLEUR is stopping after generating a
starting density.

zherk tested to be faster than standard approach
