predTransition was not passing along predicate properly. rm'd unneeded parameter. pass null if ctx independent pred. added 2 unit tests for non outer ctx check.

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.

fix various issues in TreeViewer
...
1) Issue: The tree "jumps" from a larger scale to a much smaller scale when starting dragging the scale slider.
Cause: Initially the slider was not correctly positioned. It always assumed a scale of 1.
Solution: I now calculate the initial slider position using the current scale (was 1.5).
---
2) Issue: NullPointerException when the scale slider is dragged to the very left.
Cause: The formula "v / 1000.0 + 1.0" results in a scale of 0.0 when using -1000 (left position). A scale of 0 is not supported.
Solution: in setScale I now check for "<= 0.0". In the case I use scale 1. In addition I changed the lower bound of the slider to -999, i.e. the left position represents the scale "0.001".
---
3) Issue: when scaling the scrollbars are not added/updated/removed
Cause: when scaling the preferred size of the TreeViewer must be updated as the ScrollPane refers to the preferredSize for scrolling.
Solution: now calling "updatePreferredSize" in setScale. This will set the preferred size to the "scaled tree size". It also ensures parents will be notified and the view is repainted.
---
4) Issue: only an upper left part of the tree is painted.
Cause: the TreeViewer overwrote the getWidth/Height and returned unchanged values (800x600). Only this area in painted. If the preferred size exceeded this size the remaining area was not painted.
Solution: Removed the overwrite of getWidth/Height. As one consequence the dialog will start at maximum size for large tree layouts.
