MueLu: minor cleanup
MueLu: Level: improving bad dependencies report (fixing f2881d27d6ab)

That commit did the right thing, but it did not print the last
dependency request. I've also added printing the level from which we
request the data.
MueLu: RepartitionF: changing default value to conform with UsersGuide
MueLu: EasyInterpreter: proper handling of coordinates factories
MueLu: EasyIntepreter test: ignore 'chebyshev: max eigenvalue' for comparison
MueLu: easy interface test: multiple bug fixes

* Initialize seed not for the whole test, but rather for every xml file.
  This allows proper comparison among different xml files
* When running with multiple mpi ranks, do not overwrite the output file
* Reset max eigenvalue of the matrix, which could have been cached by
  one of the previous runs
MueLu: added few more interpreter tests
MueLu: interpreter: added proper handling of nullspace

If user provides nullspace, our life is easy, and things worked just
fine. However, if he does not do that, we must construct what we
consider a reasonable approximation of one. This requires
NullspaceFactory and proper handling of all its dependencies.
MueLu: Easy interface: added filtered matrix lumping option
MueLu: RAPFactory: finishing cleanup

Commit ae73d11732a7 contains first part of moving diagonal check/repair
in RAP to validation framework. This patch finishes the task, and cleans
up the code.
MueLu: updated EI
MueLu: updated interface test to include new params of RAP and UC
MueLu: fix again RAPFactory::CheckRepairMainDiagonal
MueLu: fix handling of verbosity levels in MLParameterListInterpreter
Initialize decomposition counter with each call to Create_Mesh.
Previously done only at initialization time.
SEACAS: scripts - only do output coloring if term is xterm
