[CHORE] Util classes format and simple cleanup with generated resources (#2028)

- Did some basic formatting
- Some generated docs
- Cleaned header/impl Helper.css
- Moved PerfMonitor from util to bot/handler/command

Still a freaking mess though, but its a start i guess. Cant ask ppl to
add more or make use of those when its so messy.
