The glueing of preposition with definite article is now implemented using

NP.s : Bool => Case => Str  and   NP.w = WDefArt

np.s ! False : Case => Str is the ordinary paradigm; if the np has a
definite article, np.w = WDefArt, and np.s ! True : Case => Str is the
paradigm with definite article omitted, if np.a = Ag g Sg p.

Prepositions now have type

  Prep = {s : GenNum => Str ; s2 :Str ; c : Case ; isPrep : PrepType},

and |Prep| = |Case|*|isPrep| = 4 * 3 = 12, independent of |PCase| >= 18.

A preposition p with p.isPrep = isPrepDefArt has in p.s ! (GSg g) : Str
the preposition glued with definite article of a following np in singular.

The modified linearization categories for Prep, NP, Det, DAP, Quant,
Predet are no longer Prep', NP' etc., but Prep, NP etc. in CatGer.
They are now also used in gf-rgl/tests/german/TestLangGer.gf.
The previous auxiliary files abstract/Adjective'.gf etc. are removed.

BUT: for complexitiy reasons,
- the glueing is omitted in SlashV2VNP : V2V -> NP -> VPSlash -> VPSlash,
- SlashVP : NP -> SlashVP -> ClSlash (in SentenceGer and TestLanGer)
  are commented out.
SlashVP causes grammar compilation to crash due to memory limits, probably
because mkClause and its modification mkClSlash are too detailed.
