Constant [ExecuteInEditMode] updates in Oculus Utilities 1.15+

In Oculus Utilities 1.15+ (and possibly earlier), the Oculus code causes the Unity editor to constantly call Update() on components with the [ExecuteInEditMode] attribute. This is not the standard Unity behavior, and for complex scenes, the constant updates can make the editor run very slowly.

I tracked down the issue to a line in OVRMoonlightLoader. Commenting out this line avoids the constant updates:

EditorApplication.update += EnforceInstallLocation;

In Oculus Utilties 1.18.1, you can also avoid the issue by unchecking this checkbox: Tools > Oculus > Use Required Project Settings.

Ideally, the Oculus Utilities can avoid causing this issue in future versions. For now, however, maybe this workaround might be helpful for someone.
