[0.1.1-preview] - 2019-08-06

New GameObjectConversionSettings class that we are using to help manage the various and growing settings that can tune a GameObject conversion.
New ability to convert and export Assets, which is initially needed for Tiny.
- Assets are discovered via DeclareReferencedAsset in the GameObjectConversionDeclareObjectsGroup phase and can then be converted by a System during normal conversion phases.
- Assets can be marked for export and assigned a guid via GameObjectConversionSystem.GetGuidForAssetExport. During the System GameObjectExportGroup phase, the converted assets can be exported via TryCreateAssetExportWriter.
GetPrimaryEntity, HasPrimaryEntity, and the new TryGetPrimaryEntity all now work on UnityEngine.Object instead of GameObject so that they can also query against Unity Assets.

Various GameObject conversion-related methods now receive a GameObjectConversionSettings object rather than a set of misc config params.
- GameObjectConversionSettings has implicit constructors for common parameters such as World, so much existing code will likely just work.
- Otherwise construct a GameObjectConversionSettings, configure it with the parameters you used previously, and send it in.
GameObjectConversionSystem: AddLinkedEntityGroup is now DeclareLinkedEntityGroup (should auto-upgrade).
The System group GameObjectConversionDeclarePrefabsGroup is now GameObjectConversionDeclareObjectsGroup. This cannot auto-upgrade but a global find&replace will fix it.
GameObjectConversionUtility.ConversionFlags.None is gone, use 0 instead.

Change tracking started with this version.
