Dialog tree under Swing was a bit limited
Fixed rather obvious bug in Say action
need to fix this properly one day: for now, assrt
paved way for dialog items hiding themselves after you've used them. this gets reset, when you come back and talk.
Changed wording of property (what was I thinking?)
part of the rename of continueafterload
Two things here:
1. was was implementing the recordOfSaid speech, so you don't say the same thing twice.
and
2. is adding OnBoundaryCondition, my new callback
Added gates and points as a way of doing boundaries, and working nicely.
