fixed some printing issues.

BUG [SOLVED]: solved a bug in the ED_SOLVER. here is the log file from ED:
> TEST IN PARALLEL MODE GAVE EXACT (MACHINE PRECISION) SAME RESULTS AS EXPECTED. <

a micro-bug hidden in the arpack interface +lanczos_arpack.f90
setting info=0 and resid=0.d0 forced the toss of a random vector INSIDE the
arpack routine, using the LAPACK interface. This made the user lose contact
with the starting, random vector.
This caused serious problems in the RDMFT application and in parallel calcul
where the random vector was most proabably slightly different from call to c
to slightly different values in the eigen-vectors, ultimately leading to DIF
Green's functions with the same input bath (!!)

FIXED: we generate an identical input vector resid from fortran random numbe
using seed=1234567 (the good old hirsch-fye qmc). This ensures that all proc
have identical inputy vectors, notwithstanding their situation.
BUG HLOC [FIXED]: the bug corresponded to missing line specifying the
value of Hloc for each copy of the impurity solver in RDMFT_WRAP_ED.
That caused wrong convergence and results in disordered cases, where the
values of the local energy are important to enforce disorder in the impurity problem.

BUG CG_EPS [fixed]: in correspondance to the update of ED code with a new version
of CG fit we updated the RDMFT code. Here the variable cg_eps is set by default to
1.d-4, that is a larger number which allows for a softer chi^2 fit.
Refer to ED code git log for more info.
