Create Preview Data Dialog

Working with Advisor-type view and Action Library View, it seems we need a dialog to handle allowing Preview Data action to be executed WITHOUT pre-selecting a table or procedure.

So create a dialog that queries the user to select a table or wizard from the workspace first, then executes the Preview Data action.

Probably should include

• check for "Server Exists" (i.e. if so, then "ping()" to verify preview could run.
• Allow selection of only previewable objects (Tables and procedures)
• validate each selection. If "ERROR" then don't allow "OK" or maybe change the "OK" to "Execute"??
