Moved material editor document system buses and system components to atom tools framework

Renamed document related buses and components to have generic names
Added a base document class with default implementation from which other application specific documents can be derived to work with the document system
Added document factory function registration to the document system request bus so that each application can specify the type of document it creates
Updated all comments and messaging to only refer to documents, not materials or material documents
Updated material editor and shader management console to conform to the new buses
This will provide a first pass of a common interface for a document management system that can be shared by multiple applications
Corrected status bar message copy and paste errors
Updated all test scripts to use the new buses
