Torsions Vehicle-to-Vehicle Couplers v08

• 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.
