moved empty context chk for retry
...
altered args on reporting methods
reporting methods moved from parser to error strategy
fixed full ctx retry in DFA (used to only work in ATN)
i record conflictSet not just boolean in DFA
added debugging support to BaseRecognizer
added DiagnosticErrorStrategy

strip epsilons between alternative elements and also stripped the final epsilons before block ends. added an ATN visitor for general use. updated all of the unit tests so they pass new smaller ATNs. had to do some work in the serialization and deserialization to handle state numbers without state information. did not want to reorder state numbers during optimization.

Got validating and disambiguating predicates the way I want; widespread changes. DFAStates now have a list of predicate/alt pairs that they can test at except states. renamed Java.g4 to JavaLR.g4. LL(1) analysis did not fail when it's all predicates, which it must.
