Not all Ner variables are labeled.  NerLabel renamed NerTag; ("Tag" will now refer to a CategoricalVar associated with a Token.  New variable LabeledConllNerTag, etc.  Correctly name NerTag from Conll2003 as Iob, not Bio.
Simplify LabeledVars by not distinguishing between "WithTarget" varieties and the others.  All LabeledVars now have target variables.
Rename PosLabel to PosTag, inkeeping with NerTag change.  Also renaming files appropriately.
Make more NER taggers add NerSpanLists attr to Document.
Merge and fix conflicts.
New file doc/ICLA.txt, original from Apache Foundation.

Some additions to app.nlp.phrase.  Some of this should eventually replace similar classes in app.nlp.mention.
Renaming in app.nlp.parse:  TransitionBasedParser, ProjectiveGraphBasedParser, each with WSJ and Ontonotes prefixes.
Renaming in app.nlp.pos.  POS1 is gone.  Use either WSJFowardPosTagger or OntonotesForwardPosTagger.  More flexibility in specifying parameter loading locations.
convert the encoding of app.nlp.phrase.NounPhraseGender to UTF-8 to fix the error when compiling.

Rename to BasicTokenizer to DeterministicTokenizer.  Likewise for sentence segmenter.  Delete ClearTokenizer.  Move test over to DeterministicTokenizer and make it pass test.  Fix unicode compilation error in NounPhraseGender.
