[[ Bug 17476 ]] Use numeric sort for keys in SE variables list

Made an update to `revsevariablespanebehavior.livecodescript`

In the `setDefaultsAndCallbacks` handler, set the `sortType` for the
tree widget to `numeric`.  With the updated sort logic in the widget
that will have the numeric keys sort at the top of lists but also sort
non-numeric keys alphabetically.
