[[ Bug 21427 ]] Allow nesting of Data Grid Behaviors
If a developer needed to insert handlers to override any of the default DG behavior, they were unable to do so using a behavior. Updated the initialization code to be able to handle one or more nested behaviors between the DG group and the DG library.
Script local sResourceStack created to retain the location of the library.
The value is initialized in the _Initialize handler. All references to
_ResourceStack() were normalized and changed to the new variable (4 cases
used stack _ResourceStack() and the rest omitted stack which is included
in the returned value). Cases where a local was declared for the value were
changed to use the script local.
The _ResourceStack() handler looks at the behavior of me first and if it
does not find an expected object (button "Data Grid" of group "Behaviors")
then it will try to next level behavior until there are no more to try.
