VesselModuleManager:CompileModules() called in the Loading screen

[MOARdV]

It looks like VesselModules are being instantiated and loaded at startup now, calls to Awake() and OnDestroy() at least. That wasn't happening in KSP 1.0.4, and it causes problems if you're making assumptions (like I do) that Awake is called only once you're in the Flight scene.

They are initialized on a dummy object so that GetOrder() can be called to find out their sort order. That dummy object is then destroyed.
