Title: add most of the keywords required to parse decks used by the IRIS history matching codes

this basically comes down to adding a few flag keywords but also
requires to add a few E300 fields to TABDIMS...

the grid cannot be instantiated yet as these decks seem to use some
peculiar constructs to specify the grid data. In particular they use
property modifiers for keywords that specify the grid. (which might be
not allowed in Eclipse but work anyway...) the deck contains something
like

```
GRID

EQUALS
DX 50.0 /
DY 50.0 /
DZ 50.0 /
/
```

which Opm::EclipseGrid can't handle yet because grid properties are only
evaluated after the grid has been instantiated...
