Update DKpro components from 1.5.0 to 1.6.2

We are in process to updating to SVN snapshot version to start sharing
model data, let's do it gradually.
Update to 1.7.0-SNAPSHOT (we use -gpl- svn r518)

We need to explicitly enable StanfordParser.WRITE_POS as true.
StanfordParser: Enable PARAM_SHARED_MODEL in all instances of the annotator

This brings in quite dramatic memory usage reduction:

	without SHARED_MODEL: [INFO] Final Memory: 1575M/3291M
	with    SHARED_MODEL: [INFO] Final Memory: 1171M/2079M

Thanks a lot to Richard Eckart of dkpro for making this possible.

Let's hope we can do the same for the rest of annotators too.
Fetch 1.7.0-SNAPSHOT from ukp-public-snapshots

The user doesn't have to build the dkpro from svn on their own anymore.
Kindly suggested by Richard Eckart.

It is a little problematic since our build is not reproducible right now
and changes in dkpro before 1.7.0 may randomly affect our performance.
However, the memory savings are too massive and tempting, given that
1.7.0 release is planned for November which isn't so far away.
BerkeleyParser: Remove our own implementation

We don't use it anymore, so let's not include foreign namespace classes
if we can avoid it; for anyone who wants to switch, perhaps new dkpro
versions can handle this already, or they can resurrect this from the
git history.
desc.type.Constituency.xml: Remove, not needed anymore
Merge branch 'master' into sharedmodels
README: Remove paragraph about third-party namespace
SVGenerator: Ignore non-verb NSUBJ governors

New StanfordParser we got after dkpro update generates these (and it
makes sense, just not at all what we want here).
question.SVGenerator: Perform a proper fallback between the rules

E.g. 'What is the name of the famous dogsledding race held each year in Alaska?' should yield 'held', not give up after 'what'.
TreeUtil.getAllGoverned(): Adjust for StanfordParser now contracting out 'of' from 'prep_of'
LATByFocus: Special-case LAT 'many' as 'quantity'
LATByWordnet.genDerivedSynsets(): Accepts hypernym synset, not synset to derive hypernymes of

This will allow to generate extra non-hypernym LATs too.
LATMatchTyCor debug print: Print LAT text instead of origin word text
*.LATByFocus: Fill a new LAT.pos attribute for more precise tycor
LATByWordnet: Consider only wordnet entries of POS that matches LAT.pos
LATByWordnet: To generate nouns from adj/adv, use ATTRIBUTE inst. of NOMINALIZATION

hot -> temperature rather than hot -> hotness.
AnswerScoreLogistic: Retrained with new parser etc.
Merge branch 'sharedmodels' into bettertycor
AnswerScoreLogistic: Retrained with new heuristics
