Add chat messages for bans, mutes and kicks plus reasons

[AnotexX]

• when someone is banned, include an endless string at the end of the command where someone can type the reason
  -potential formatting: "Name" was banned by "admin name" because "string" - announced in chat by the server
  -when someone is muted or banned, add a number value with a defining letter for units
  -potential formatting: /mod banSPS "name" 7 d
  -This would ban someone for 7 days. d for days, s for seconds, m for minutes, h for hours, i for infinity. Something like that
  -These two suggestions would both modify the same commands.
  -Also announce kicks in chat, and the kicker
  -Add approximate time remaining in ban in server join attempt message for banned person
