Ger: improved infinitives (and passives); tests with more verbs in testing/german

- NP: added field isLight in order to push negation behind light nps;
  this had been done in gf-3.9 using field isPron, but isPron is now
  used to put accusative pronoun before dative pronoun. Removed field
  adv: adverbial extensions cannot be extracted (todo: also for CN).
  Reduced isLight*isPron to w:Weight with 3 values: WPron, WLight, WHeavy.

- added param Control and field ctrl:Control to classify V2V-verbs into
  subject- and object-contol verbs, use ctrl to make reflexives agree
  with subject resp. object in VPSlash, and refine ComplSlash.

- Verb: new versions of ComplVV, SlashV2V and SlashVV to give better
  (nested) infinitives (extracting infzu and correcting object order).
  a) nested SlashVV doesn't work properly;
  b) SlashV2VNP may have to be commented out to prevent a stack overflow
     when compiling.
  Intended change of SlashV2VNP in tests/german/TestLangGer could not
  be tested due to size problems with the compiler.

- VP: changed field a1 : Polarity => Str to a1:Str to collect the adverbs
  coming before negation, using (negation : Polarity => Str) in mkClause.
  Use objCtrl:Bool instead of missingAdv to let reflexives agree with object.

- ResGer: insertObjNP reorganized, infzuVP added

- DictVerbsGer: some corrections (helft -> hilft, *sprecht -> *spricht)

- Some potential passive rules in tests/german/TestLangGer|Eng

- ExtraGer needs to be cleaned up with repect to the modified mkClause.
