Added OS:Fan:ZoneExhaust to IDD.  Kyle, I'm not totally sure about the System Availability Manager Coupling Mode Field.  I kept it for now.  I didn't build yet.  I will do that now after commit.
Adjust thermostat translation

Removed thermostats from the idd object types to translate because thermostats
will be explicitly translated within translateThermalZone.
This removes any possibilty of orphan thermostats ending up in
the idf file.

Add VRF Controller
Factor RefrigerationSystemGridView into base class

Create GridLayoutItem which is a QGraphics item to layout other
QGrahpicsItems in a grid view.  It works with OSListController.
Extracted the common functionality out of RefrigerationSystemGridView
and moved it to a "shared_gui_components" class.  This will be reused
for VRF grid view.

Factor out new class OSDropZoneItem

This is the same as OSDropZone but made to work with QGraphicsScene
instead of QWidget.  Much of the custom painted interface in HVAC uses
QGraphicsScene.  OSDropZoneItem was factored out of
RefrigerationSystemDropZone so that it can be reused in VRF interface.
Add feature to drop terminals on VRF system
