Handle OnUser1-4 outputs

[rtldg]

Maps with outputs that do AddOutput,OnUser1 ..../FireInput1 ... aren't too common. I actually can't name any that I'm aware of and nobody seems to post about issues related to maps with them [failing to be checkpointable/segmentable]. Except soda.
Tony Montana has prefab/test-map at https://gamebanana.com/mods/2153.
Anyway, we can stuff more ArrayLists in the plugin to handle these with some special casing of the events, and simultaneously break any plugins (bhoptimer) that use GetClientEvents/SetClientEvents [unless they're updated].

I'll still need to do some double/triple -checking that it actually works since I've only been testing on prefab/test-map multi_system so far. EDIT: Tested on bhop_vlim_fix too and it was fine.

EDIT: A list of maps that use Tony's prefab:
