Default property track settings for Spot Light OuterConeAngle don't work

The outer cone angle will not have a default track created for it when it's added as a default property in the project settings. This seems to stem from the property having a setter function, and being on a component. See the linked UDN for more details.

1. In Project Settings under Plugins > Level Sequencer add a new element to the Track Settings array
2. Select SpotLight as the actor class and add an element to Default Property Tracks
3. Set the component path to LightComponent0 and the property path to OuterConeAngle
4. Open a sequence and add a spotlight

RESULT

No track will be created for the OuterConeAngle.
