Subject: [PATCH] Improved Timings System
Enables "Timings on Demand" so you can enable/disable timings without server restart.
Tracks timings on sync events a plugin registers (Single and Repeating)
Tracks how many ticks a timed area has caused the server to lose due to taking too long.
Enables automatically pasting to paste.ubuntu.com so you can quickly review the results on aikar.co/timings.php
