--TODO: use SSCSM to reduce lag and network trafic (just send modchannel messages)
--TODO: fadeIn and fadeOut animation (needs engine change: SSCSM or native support)
--TODO: allow obfuscating text (needs engine change: SSCSM or native support)
--TODO: allow colorizing and styling of part of the text (NEEDS ENGINE CHANGE!!!)
--TODO: exactly mc like layout
--Note that the table storing timeouts use playername as index insteed of player objects (faster)
--This is intended in order to speedup the process of removing HUD elements the the timeout is up
