Fixed bug with recent queries not loading from previous sessions.

Added the transform name for a query to the recent queries view.
Made sure that changing simple queries options don't create a new entry in the queries history
Fixed some problems with highlighting the current tab in main navigation
Cosmetic
Removed New Dynamic Query from the New button (we now have the Query tab), replaced it with New Transformer.
Added an "Add Transformer" button to the Query window toolbar.

Transformer option is now shown below the Sort By fields in the main query window.
Better error handling in Studio for compilation errors when editing a Transformer
