Private Chat

Added ability for players/admins to send a hologram message to a players location. The hologram will delete itself after 10 seconds . A notification will be sent to the target player, letting them know the hologram was sent to them. The hologram text code has the players displayname and follows the colors set for player channels or staff based channels. Therefore any player with the channel.staff permission has their hologram text show up as the color setting for staff chat channel.

- Added c.holo permission for players to send each other holograms

- Made help commands more specific.(Some were not detailed enough)

- Fixed bug where chat loses color if it exceeds one line
