Drop Shadows on Actions/Icons (Images/Hotspots) from Media Library

hvaughan-2540

- Can we have the ability to switch off the drop shadows from icons/actions added from the CenarioVR media library? The svg files themselves don't have shadows, so it must be CenarioVR adding them on. Some don't have shadows but the majority seem to.

- After placing an action/icon and double clicking, you have the ability to change its colour but there is no option to select the colour from the custom colours palette, can this be added?
