add the missing TABDIMS keyword to the live oil and wet gas unit test data files

these are required for the new parser. (without them, these files
would be invalid AFAICT, but I'm not an Eclipse file format expert...)
Merge pull request #572 from andlaus/add_tabdims_to_some_decks

add the missing TABDIMS keyword to the live oil and wet gas unit test data files
convert the EclipseGridInspector to opm-parser

that one is completely unused in opm-core (*booo*!), but used quite a
bit in dune-cornerpoint and dune-porsol, so let's keep it for now...
CornerPointChopper: add methods opm-parser'y methods
add opm-parser variants for the incompressible property classes
remove the import_rewrite example

that one was quite specific to the old parser and would thus require
more work to convert to the opm-parser than what it is worth the
effort. If you _really_ want to keep this tool, ping me and I'll port
it...
convert the examples and the tests to opm-parser
