Added new alias for chat commands. Can now use /nm as well as /nav

Added new parse type for range (R.)
- Example "C1 (R.300)" or "C1 [R.300]"

Added a few new chat commands:
-toggle: show/hide markers
-set: update range
-close: toggle show nearby markers
-intersect: create gps point at view intersection

Implemented help command to actually show something useful

Added two new modes, showing close markers only and showing only partial spheres/markers.

Close Only uses a new config setting to only show markers that are closer than this distance from the player, defaults to 100,000m (100km).

Partial markers only shows the segments of the wireframe that are close enough to the player. This also can be controlled by a config setting.

Both have toggles as hotbar actions.

Added chat commands:

• add <range> <name>: Adds a marker at the GPS point with <name> and radius <range>
  
• remove <name>: Removes a marker with the matching <name>
  
• list: Lists all active markers in chat
  
• help: Shows a help message (placeholder for now)
