I'm refactoring proximity monitors and fields, removing lots of bloat from both that's hardly even used. Proximity monitors no longer generate effect objects to track the surrounding area, should be less cpu expensive and easier to maintain (or phase out), read and use. This PR also adds a couple components which may be needed for future stuff (for starters, the mirror reflection PR #62638 could use the connect_range comp) Improving old old, ugly old code and adding some useful backend components. Tested and working.
