Torsions Vehicle-to-Vehicle Couplers v08

Changes:

1. Modular chain! Using the parts config menu you may now select chain lengths from 1/3 of the previous norm up to over 4x as long.
   
2. Improved deformation! Completely reworked flexBody mapping, it's now way, way better. In my opinion this new setup is better than the Giant Flail's current chain deformation.
3. Detangling / movement accuracy improvments. I'd appreciate feedback on this. I've added a bunch of beams to limit the chain's movement. The...

MODERATION : removed not used files

• D15 parts changes:
  • Renamed "short chain - female" to "Short Towstrap (Female)"
  • Added very basic flexbody (mesh) to "Short Towstrap (Female)" so it's not invisible anymore. Tweaked jbeam to accommodate my mesh.
  • Removed "Tow Hitch - Female" from D15. I can add this back, but I doubt that anyone was using it since "Short Towstrap (Female)" is generally better. This had just become unnecessary cruft in the menu at this point.

• Added real preview image.
• Moved couplers into slots.
• Added additional coupler types. Couplers now include:
  • Female ball (attaches to standard hitches)
    
  • Makeshift fifth wheel peg (for vehicles such as the Semi)
  • Male ball (Difficult to use, but workable with effort - attaches to standard trailers.)
• Added 3 selectable configs w/ a default of female ball-to-ball on double-click.

Minor update:

• Added a second hitch mesh to the Giant Chain. Previously the Giant Chain had only a single hitch and chain links so one end of the chain appeared to have a chain link attaching directly to a hitch. This is now corrected.

Removed an extraneous jbeam file that was causing problems for some users.
