add a cmake test to check if the used file system is case sensitive

And fix the unit test for INCLUDE. This should make the test pass on
case insensitive file systems like the one of MacOS X. (Who uses that
anyway? ;))
fix the PVCDO keyword

this was just a copy of PVTW and is quite embarassing. We should
prevent this in the future by making sure that the filename
corresponds to the JSON name when generating the C++ keyword list...

Removed extra "," from WELTARG
Merge pull request #192 from andlaus/check_filesystem_case_sensitiveness

add a cmake test to check if the used file system is case sensitive
Added keyword SMRYDIMS
Added getDataSize() method to DeckKeyword.
Added assert of the size of the vectors used to create a CornerPoint grid.
add numTables() method to the table classes

For SimpleTable, that is simply the number of records in a keyword, for
MultiRecordTables, it is the number of _empty_ records.

this patch makes supporting multi-PVT easier and cleaner.
add some comments to the capillary pressure retrival methods of S{g,w}ofTable

that's because the Eclipse capillary pressure definitions
inconsistent: SWOF specifies the "water-oil capillary pressure" as $p_o
- p_w$, while SGOF uses $p_g - p_o$ as the "oil-gas capillary pressure".
table tests: expand them considerably and actually run them

In the current version, the runTimeMapTest binary was run because of a
copy-and-pasto. oops.

Also, not all of the tests pass but that is because of another problem
of opm-parser for which I don't know a good fix: It currently seems to
be impossible to specify empty records if there are non-defaulted
items in the JSON keyword specification, but such empty records are
used as table separators by Eclipse...
rename SimpleTable to SingleRecordTable and SimpleMultiRecordTable to MultiRecordTable

because what's simple is in the eye of the beholder...
fix the "number of table" calculation for multi-record tables

It turns out that the empty-record detection worked fine, but that the
last empty record of a keyword is ignored by opm-parser for reasons
which are not clear to me...

Now all unit tests pass.
Added DEPTHZ as alternative to TOPS.

Eclipse grid
EclipseGrid: do not add integers to the addresses of const char* pointers

this results in funny error messages and (if the integers are large
enough) in segfaults. thanks to @atgeirr for pointing this out!
