Notes:
1. { } = optional
2. Triggers in italic are reserved for rankers only
3. rank = Easy / Normal / Extra / Hard / Lunatic / Phantasm
4. Other than add, del, update and rename functions which use exact nick match by default, use "nick" for exact nick match for other functions (e.g. !rank "guuchan" chars)
5. If you want your ranking to be locked as "N/A", /msg guuchan
