Subject: [PATCH] Further improve server tick loop
Improves how the catchup buffer is handled, allowing it to roll both ways
increasing the effeciency of the thread sleep so it only will sleep once.
Also increases the buffer of the catchup to ensure server stays at 20 TPS unless extreme conditions
Previous implementation did not calculate TPS correctly.
Switch to a realistic rolling average and factor in std deviation as an extra reporting variable

Subject: [PATCH] Player lookup improvements
Minecraft and CraftBukkit both use Arrays to store online players,
and any time a player needs to be looked up by name or UUID,
the system iterates all online players and does a name or UUID comparison.
This is very ineffecient and can reduce performance on servers with high player count.
By using a map based approach for player lookups, player lookup should
be consistent in performance regardless of how many players are online.
