Remove Deprecated Objects Array

[jshughes]

💡 Description

The IMTool/LDDTool code no longer uses a deprecated objects array (deprecatedObjects2) and so it can be removed. This array provided a list of classes, attributes, and standard values that had been deprecated. This information has been moved to the Protege database. In addition to removing the array , old code and references associated with the array have been removed.
