More Long ID Differences

Just pushed the updated code that manually creates the consistent long
IDs.  Not sure what to call them - they are still pretty much a long ID, in
the same form as the long ID that is used for behaviors but derived
differently.

Bulk of the code for the stack is here:
https://github.com/bwmilby/lc-misc/blob/master/ScriptTracker/ScriptTracker_Scripts/stack_ScriptTracker_button_id_1003.livecodescript

I've also added an option to perform a sync when saving the stack using a
front script that intercepts the SaveStackRequest.
