loosen tolerance a bit to avoid failing tests on certain archs
write out the reservoir state to the eclipse binary format

most code was shamelessly ripped from opm-core's EclipseGridParser,
but there are some additions (e.g. grids specified using the D[XYZ]V
Eclipse keywords can be used).

The code is located inside the new class "BlackoilEclipseOutputWriter"
(should probably renamed) and hooked up in
SimulatorFullyImplicitBlackoil and sim_fibo_ad.cc.

Also be aware that, to make this code work properly, the newest master
version of ERT is required (i.e. one which includes commit
5e4e9661720). In this context, I would like to thank Joakim Hove for
his support!
write out water injection and oil production rates

Currently, it still writes out whatever conservation quantity which is
used by the solver (which is probably the mass of the oil/gas
mixture). TODO: convert these solver rates to "pure oil volume without
gas at the surface" and to "gas volume at the surface" rates.

thanks again to Joakim Hove for the pointers where to start kicking!
