Waypoint improvements

[m-sarabi]

A few enhancement ideas for the /cwaypoint command:

Show/Hide waypoints

The /cwaypoint show <name> and /cwaypoint hide <name> commands to show or hide a waypoint.

Set waypoint color

The ability to set a color for the waypoints, instead of the default yellow color. It can be:

• /cwaypoint color <name> <hex color>
• /cwaypoint add <name> <pos> [<dimension>] [<color>]

Auto hide waypoints

A config option like /cconfig clientcommands hideWaypointDistance set <value> with a default value of 0. If the player is closer than this value to a waypoint, it will disappear/fade, and if the player gets further, it will reappear again.
