> This contains the following:
> - Nested changes or invalidations using ExpressionHelper are delayed until 
> the current emission completes
>   - This fixes odd change events being produced (with incorrect oldValue)
>   - Also fixes a bug in ExpressionHelper where a nested change would unlock 
> the listener list early, which could cause a 
> `ConcurrentModificationException` if a nested change was combined with a 
> remove/add listener call
> - A test for ExpressionHelper to verify the new behavior
> - A test for all *Property and *Binding classes that verifies correct 
> listener behavior at the API level (this tests gets 85% coverage on 
> ExpressionHelper on its own, the only thing it is not testing is the locking 
> behavior, which is not relevant at the API level).
> - A fix for `WebColorFieldSkin` which triggered a nested change which used a 
> flag to prevent an event loop (I've changed it now to match how 
> `DoubleFieldSkin` and `IntegerFieldSkin` do it
