Feature: Optifine CIT Cache

Written by @nea89o

Gain 20-50% extra performance while using a skyblock cit pack
Will not work in dev environment!
/shoptifinecache shows stats about the cache over the last 100 ticks

Test in hub 1 looking forward while using furfsky
No cit pack

With cit pack

With cit pack and option on

Conclusion is that the setting works well but cit packs are still horrible for performance

Fair enough, but it's unfortunate that it's in a cheat mod, so we can't exactly go around recommending it to people.

Ill port it with another performance improvement patch i am working on into its own standalone mod

I feel that this is the best solution and sorry for any problems I caused through this pull request that was never my intention.

More standalone mods is always a good idea.
