new reference solution for diffusion_flash

the file is basically the same, but for some reason the simulation
takes one time step less...
co2: fix typos
newton method: deal with failures during linear solves and updates.

this was a regression compared to the split newton method/newton
controller code.
extend the changlog entry for the recent newton infrastructure rework
print the time step size when serializing the state of the simulation

this makes it easier to restart with exactly the same parameters.
reduce the singularity limit for FieldMatrices inside the linear solver

this prevents issues with the ILU preconditioner.
fix sign error in energy module

the temperature gradient at the boundary had the opposite
direction. this lead to screw-ups for heat conduction at the boundary
if the energy module was enabled.
brine-co2 fluid system: remove a superfluous else statement to decrease the indention level
start: handle errors while parsing a ini file more gracefully

print the message of the exception thrown so that it is easier to know
what's going on.
Added first approximation for the thermalConductivity in the h2oairfluidsystem.

As a first step, this is valid only for 0.1 MPa and 293.15K. However,
the complex formulation for conductivity of h2o is computed
correctly. Also fix a typo in the documentation.

Revert "Added first approximation for the thermalConductivity in the h2oairfluidsystem."

This reverts commit c7107aae26cd3a89f1d33bb9e353a6fe327b87e3.
change namespace from Dumux to Ewoms

eWoms hereby declares full independence. Humor aside, the main
technical advantage of this is, that it is now possible to easily
install both, Dumux and eWoms on a system using a package management
system without bad tricks.
components: some small fixes

- We now use the same thermal conductivity for dry air as dumux
- Documentation cleanups for the water component
update the change log for the namespace change
make the autotools build system non-recusive

this allows much better build time parallelism.
Makefile.am: build the executables into the same directory as their repective source file
Get rid of some continue statements. Fix indention. (corrected and reviewed by mwolff)

Minor changes

-remove disabled acess functions in multiphysics cell data
-enable "EnableCapillarity" Property for Multiphyiscs in simple update function
-avoid wrong output: * set error correction to 0 if it is 0
 * upwind information in simple subdomain set for both phases
 * First episode has index 1 and not 0 => fix first timestep size in fvpressurecompositional
