adapt to the renames of the table classes in opm-parser

basically, "Opm::SimpleTable" becomes "Opm::SingleRecordTable".

adapt to the renames of the table classes in opm-parser
Added missing line (parser conversion).
Use ENDNUM and prepare for IMBNUM.
Make use of keywords SATOPTS and EHYSTR.
Reset gwseg as the model for endpoint scaling.
ENDNUM: changed default value and jtab-logic

Default value changed from 'no scaling' to 'use table 1'.
Range of jtab changed to [-1,#tables-1].
Fix to make EQLNUM consistent with ACTNUM.

This should eventually be integrated in the parser.
Inserted some documentation.
Initialisation of EGLNUM (analogous to e.g SATNUM)
Proper interpretation of ENDNUM and IMBNUM fields.

Made consistent with grid discretization.
Removing a few bugs ...

Endpoint scaling - taking advantage of the new parser.
Supress signed-unsigned comparison warning.
Merge pull request #589 from atgeirr/fix-comparison-warning

Supress signed-unsigned comparison warning.
remove EclipseGridParser compatibility methods from all classes
attic: remove all files which required EclipseGridParser

since the attic is the place for bits to rot silently, I doubt that
this code would have been of much contemporary use anyway. Even if it
could be made to compile, porting it to opm-parser would hardly be
worth the effort. If you are nostalgic and want to see how things were
done in the olden days, use `git show $COMMIT` or `git log --stat` or
`git log -p` and search for "EclipseGridParser"...
remove the EclipseGridParser class

RIP!
rename all "newParserDeck" objects to "deck"

The "new" parser is now "the" parser...
