controllers push to the WebGL view directly, drop ClientGameRunner relays

BuildPreviewController and WarshipSelectionController now take the WebGL
view in their constructor and call view.updateGhostPreview /
view.setSelectedUnits themselves instead of emitting bus events that
ClientGameRunner forwarded. Splits the old mountWebGLDebugRenderer in
two — createWebGLView builds the view up front so the renderer can wire
controllers to it, mountWebGLDebugRenderer does the per-frame plumbing
after the transformHandler exists. GhostPreviewUpdatedEvent had no
remaining consumers and is removed.
