also eat keywords containing lowercase letters

The Norne deck actually exhibits this atrocity in form of the
'fluxnum' keyword in the file 'INCLUDE/PETRO/FLUXNUM_0704.prop'.

I don't know if Eclipse cares about the case of the keywords, but
opm-parser currently does for sure. (If Eclipse turns out to be
case-insensitive, the easiest fix for us is to just make all keywords
ALL_UPPERCASE...)

Cherry pick from #339
Revert "also eat keywords containing lowercase letters"

this was inadvertedly merged. the real fix is to make the parser
case-insensitive...
make the parser case-insensitive

i.e., make keywords ALL_UPPERCASE before using them because Eclipse
seems to be case-insensitive (although this is one of its undocumented
features...)

EclipseState: make specifying anything which requires a grid an error if no grid could be instantiated
Split EclipseGrid in dimensions and cell info.

In many cases the only required information in an EclipseGrid instance
is the cartesian dimensions. To facilitate simpler testing - and not
have to create a full dummy grid the dimensions have been internalized
as a separate nx,ny,nz triplet. With this commit it is possible to
instantiate a grid with only dimensions, and no underlying ecl_grid_type
pointer.
Using shared_ptr<EclipseGrid> instead of bare EclipseGrid *
EclipseGrid - check content of c_ptr before use

This commit contains quite large changes to the EclipseGrid. The main
functional change is that the access to the ecl_grid_type pointer is
protected. In addition there are 'white space' changes due to methods
moving around and some methods have been marked static.
Check that exception is raised if PORV is initialized without grid.
Removed unused dummy grids in test deck.
Removed unnecessary default values.
Removed EclipseState::hasGrid() method
Changes to emacs file .
Added test of EQUALS keyword auto creation.

.dir-locals.el: remove Statoil developer setup specific commands

my emacs always asks me whether I want to apply these settings as it
consideres them unsafe. Furthermore, I use a different directory
structure, so these settings are useless to harmful for me.

If you want to keep these settings around, please move them to ~/.emacs
