[Open Assets] Random Monitor v3.2.3

apparently I messed up ring randomization and never noticed, fixed

ring monitors now randomize, you'll have to use a custom monitor for these
added function:
RandomMonitorAddRing

it now prints a message when a monitor is added to the list
that's it

eggman monitors became shields
that went over my head like a ballistic missile

I missed an ) which broke something

+ new lua functions for adding powerups and monitors (which hopefully don't break at all)
RandomMonitorAddShield(MT)
RandomMonitorAddPowerup(MT)
MT being the mobj type for your monitor

I redid script, you can now add your own monitors

example:

if not RandomShieldMonitors
rawset(_G, "RandomShieldMonitors", {})
end
RandomShieldMonitors[10] = MT_YOURSHIELDMONITOR
