Support variants property on components

Also the following tasks are done in this commit:
- show active root component properties in the inspector.
- fix a crash when opening the light scope drop down.
- remove a lot of dynamic casts and useless code and cleanups, mainly
from the inspector classes. There is still more dynamic casts and memory
leaks that should be tackled in another commit.
- move a method to more appropriate place.
