* Updated VisualParamGenerator to generate a lot more params (from Group-1), and the AppearanceManager code to ignore non-Group-0 params

* Can cancel and re-request single image downloads now (still need to add this to multi-image downloads)
* Added a hacky re-request timer to AssetManager for image downloads (we'll see how it goes)
* Couple of tweaks to make AppearanceManager.SetPreviousAppearance() slightly more reliable
* Updated VisualParamGenerator to match what we are currently using as the VisualParam class
