EGPlates

Implemented queued loading, so performance is more normalized; previously, entering an area with many units could cause tremendous slowdown from loading said units.  Now there is a constraint which will limit the number of units loaded per frame.  This will cause the massive spike to go away (for EGPlates; other addons that load units without a queue will cause issues), and instead spread the load across many frames.  However, due to spreading out the loading across frames, it may take a moment for various nameplates to load.
