- Fixed bug in auto-detection of q-points for _ELPH project.
- Fixed bug in X_os for systems with fractional occupations when
  X%cg_percentual<100 %.
- compilation issues fixed

Additions:
- Added double versioning system. Devel revision used for internal compatibility while GPL revision
  used for reporting.
- wrapper's interfaces used by more subroutines

Changes:
- Added novel auto-parallelization scheme.
  If yambo is run without giving a specific parallel structure than this is auto-created.
- Configuration report message changed
- fragmentation done by default on kpts. To avoid it run yambo / X2y -U (X=a,p,e)
- WF_splitter
  fragmentation on bands also by default if a single wf file is bigger than 10 MB,
  which means about more than 350 bands for kpt. The previous limit (400 MB) was too high.
  To avoid it run X2y -b $n_tot_band, with $n_tot_band the total number of bands in your database.
  Notice that yambo is not able to do fragmentation only on the bands.
  If the bands fragmentation is activated so it is the kpts fragmentation.
  NETCDF write WFs in single or double according to the value kind of wf.
  So, in the calculation of the DBs sizem DP has been replaced by SP with
  a factor 2 due the complex nature of the WFs.
