Get rid of the OverlayEffectsComponent stuff (#3010)

Browse Source 
* Get rid of the OverlayEffectsComponent stuff because it just ended up creating workarounds for it's bugs, without removing any functionality

* Flashes and Flashbangs use the same code now (the Flashable path because it's better)
