40a90b551a Allow error recovery to look all the way to the bottom of the stack 
Previously, there was a bug where the first node on the stack
would never be popped

1a5d5b3156 Make ambiguities resolve deterministically 
In the future, they should resolve according to some kind of dynamic
precedence annotations provided in the grammars. For now, this at least makes
them fully deterministic, so that tests won't fail due to ambiguities resolving
differently after undone edits.

30b6530fd1 Account for parse stack merges when shifting 
Previously, when the parse stack was split into 3 or more heads, it was
possible for head 3 to be accidentally skipped if head 2 merged with head 1.

0b1d70db34 Always resolve ambiguities immediately 
No more ambiguity nodes.
Also, when merging parse stacks, merge their successors if needed.

f7e4445358 Handle goto actions after reductions in a more standard way 
Rather than letting the reduced tree become the new lookahead symbol,
and re-adding it to the stack via a subsequent shift action, just
add it to the stack as part of the reduce action. This is more in
line with the way LR is described traditionally.

647c3e2010 Add tests for editing all language examples 
This drove out several fixes to the incremental parsing algorithm.
There are a few examples which still don't work and which have
been explicitly excluded, for now.
