Some last big changes for v2.

- Add timeoutlength command
- use sendMessage instead of chat
- add permission scheme for e.g. PEX
Reorder the code here to simplify.
Implement the ability to timeout a person.

/timeout now accepts a player name. This can be used to manually
put a player into a timeout.
Don't really need an extra enable message here.
Fix location of this code, and make it work.
v3. reword messages for better RP.
Update readme, consistent spelling.
