Add AF_OriginConceptBy{Subject,Focus,NE} (and corresponding ClueConcept flags)

It seems that especially Subject concept clues have much higher
probability of carrying the correct answer than others; it is in general
rather surprising that AF_OriginConcept has a big negative weight in
scoring, this might make things more interesting.

doc/TODO.md: Revamp, update, roadmap for 1.0
doc/TODO.md: Some more immediate ideas

We have two branches f/quantitylat and q/cluefeatures which we can't
merge as they cause overfitting. These TODO items are aimed at fixing
that to get them in mergeable shape.
LATByFocus: Generate measure, not quantity as FocusProxy
LATByWordnet: Generate noun derivation Wordnet LATs with specificity 0
LATMatchTyCor: Fix AF_tyCorA* features not always generated

Try recursion in LATMatchTyCor.getBaseLat(); baseLat points only to the
immediate parent LAT, not to the originating LAT.
