Get rid of agentdata system all together

[ensiform]

This extra entity system is very wasteful and we can actually (re)use a lot of fields within the entitystate and playerstate if needed, as ET has a ton of extra free unused fields on player types and in general in ETF they are not used at all.

• Restructure disguise/invis to use new fields
• Remove agentdata code all together
• See Move persistent class/team for corpses to new entity type #33
• Make gas hallucinations use a different local cache since agentdata won't be necessary anymore

Hello, please excuse me if I'm totally wrong, but wouldn't be UEIDs perfect for fixing this?
Tremulous uses UEIDs.
I assume it would be hard to completely rewrite ETF's entity system to match the Tremulous style of how to deal with entities. Anyways, would it be worth at all?
I have to admit I don't have the skills, to make that happen. It just crossed my mind and I followed Tremulous for a while and saw that they really spent a lot of time to improve the entity system and memory managemant.

I do not see the relevance to this "problem". There is no need to have extra entities at all.

Ah, ok, it seems I didn't even understand the problem. Sorry for that.

I have not currently pushed the changes yet, but I have already fixed the corpse task and the gas hallucination task. Haven't pushed because not yet confident I have done it right without more clients available to testing.
