Implemented split combat levels

A split combat level (e.g. 50+5) will be displayed for a player when the player is on a PvP world and does not have a summoning pouch or a familiar summoned.
A split combat level will also be shown if the player is on a world with wilderness PvP enabled, the player is in the wilderness, and does not have a summoning pouch or a familiar summoned.
If the world is a PvP world, display other players' combat levels in white if they are outside of combat range, or shades of green/yellow/orange/red if they are within combat range.
If the world is not a PvP world, always display other players' combat levels in shades of green/yellow/orange/red.
