Remove slave dof canceling: Does not make difference with SPGRID, fails with YASP
[msfem] VTK output only done when parameter is set
[params] Use "data" as directory for data
[locProbSolver] Renamed method for the sake of readability
Removed local problem assembly+solve from MsFEM matrix assembler

This is done outside now.
[fem solver] Removed superfluous output
[locProbSolver] Removed superfluous output
[msfemSolver] Output cleanup
[msfemSolver] Get values for solver from parameters and use better defaults
[msfemSolver] Measure time for assembly, solve, etc distinctly
[locProbSolver] Output time for saving local problems
Don't use Dune::Timer, I don't trust it

[fem] hooray for reusing existing and working code
