The fvGeometryVector builds all sub control volumes, sub control
volume faces and fvGeometries; where the fvGeometries are merely
providing iterators over scvs and scvfs of an element.

This becomes obsolete because the volume variables are now only computed
twice per dof in each newton iteration, a necessary update and one time
with a deflected solution to compute the derivatives correctly.

* Make VolumeVariables a global vector
* Make FVElementGeometries a global vector

Results in 5% speedup for the 1pcc test (100x100) and
a 20%! speedup for the 2pcc test.

[fix/tutorial-exercise1f] Exercise 1f makes more sense now

The changing constitutive relations task in exercise 1 previously was about
exchanging the EffToAbsLaw with a LinearMaterial law. It makes more sense to
replace the RegularizedBrooksCorey.
The description in the handbook was adapted accordingly.

Thanks to Martin for fixing a c&p bug.

The parameter parser previously needed a TypeTag traits template argument only
to get the parameter tree type although a parameter tree is already handed it.
This was done to avoid an usused parameter message otherwise issued if the parameter
macros (which need the TypeTag) are not used. Twisted :/ (can't we refactor the parameter system?)

The new implementation has an optional input file name parameter which is taken from the
parametertree if it was provided as command line argument in the default start method. You
can also supply a specific file now statically in the code. If no name is given, the
parameter parser defaults to the <exectuable>.input pattern.

[gitignore] Ignore "Testing"

Once in a while a "Testing" folder occurs in my repository. I guess it is related to the build system / testing. Therefore I added to gitignore. Hope this is not breaking someones folder structure.
