feel/input config updates following max force bug fix

[tacodevhaydz]

• changes to the pedal feel curve editor to better match pithouse

  • nodes now draggable on both axes
  • anchor top and bottom nodes
  • put force and deadzone vertical sliders next to input curve editor for ease of use when adjusting pedal feel
  • added additional adjustment nodes as updated firmware allows one additional x,y point
  • range clamping to adjacent nodes

• changes to the sim input curve editor to better match pithouse

  • scales curve shape when adjusting top node on x axis
  • only top & bottom nodes are adjustable along x axis
  • other nodes are y-axis adjustable only, unless scaled by top/bottom node adjustment

• UI tidy up to deal with large scale config changes

• added 'trend' line to damping curve editor (visual only)

• updated profile load/save calls to make sure latest values are persisted in profile and on UI reload
