make the regex test more thorough

it seems like the std::regex delivered up to gcc 4.8 has problems with
constructs such as ".+". (at least if they appear at the end of a
regex...)
  Computes saturations based on depths
    For constant capillar pressure function the saturation is
    determined by cell depths:

    Sg_max, Sw_min
    ----- goc ----
    Sg_min, Sw_min
    ----- woc ----
    Sg_min, Sw_max
    Implements initialization for constant capillary pressure functions

EclipseWriter: attempt to fix the well summary output for activeWells != totalWells

The summary files now always features all wells which ever appear in
the deck in every timestep (even if they are not specified for the
time step). This _should_ fix the crashes when writing Eclipse output
in the Norne deck, but I have no idea if the resulting summary file is
correct. More testing would be thus highly appreciated...
