SmartClient 5.5.1 patch for duplicate entries in hierachical menus

[Isomorphic]

This patch is a workaround for a bug in the 5.5.1 build where databound hierachical menus (menus that load their submenus from a tree structured datasource) would occasionally include duplicate entries in the submenus.

This patch should be applied by one of the following methods:
- simply adding a <SCRIPT> tag with the content below, after you load SmartClient
- saving the content below into a .js file and including this file via a <SCRIPT SRC=...> tag, after you load SmartClient

It will automatically disable itself with future versions.
