Store edits in trees, not by splitting stack
...
This allows for multiple edits per parse, though it is not exposed through
the API yet

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.

I want to re-use the stack data structure for storing the
re-usable nodes from the previous parse tree during an edit.
In this case, the stack won't conceptually start at position
zero, so the name 'right_position' doesn't make sense.
