0.9.3 waypoints and background

TLDR:
Waypoints are less clunky now, navigation in warp is a bit easier and the background in warp is now sometimes pink.
Changelog:
Waypoints can now be set from any plane to any other plane, automatically being translated to the plane you are in.
Waypoint now always shows its coords in HUD.
Neighbour sectors coords show RSP pos in Warp.
Neighbour and waypoint are prefixed with [WARP] in warp.

Procedural background image is now always bright pink in warp.
WarpSpace is now a core mod for HUDIndicatorOverlay and not compatible with any other mods overwriting the same class.
