updated descriptions, upgraded 4 ropes sliders to prevent rope length overflow as much as i could

None Provided

Add 4 ropes slider option for slider length ( i needed it )

- Fix suspension arc not showing if adv ballsocket option is disabled

- fixed a lot functions not being loaded in singleplayer because autorun/server is not loaded... -> functions have been re-moved to the stool folder

- Add visual arc for 2 ropes slider to show their range, accurate most of the time
- Change colors for visual indicators
- Rename a few variables in DrawHUD for clearer purpose (not complete)
- Suspension Direction visual indicator now changes length depending on the suspension extension you've chosen. (needs to be updated for when you choose to not limit the suspension extension). Was renamed to Suspension (UP).

- Fix wrong name for subcategory in advanced ballsocket options ('Extension settings' -> 'Adv. ballsocket settings')

- You can now create suspensions whose up/down and wheel rotation directions are the same. This doesn't work for 2 ropes slider as they would curve in unexcepted directions.

- Fix some convars not being updated because of menu function override (for 2 DComboBoxes)

- Update menu, settings are more organized. There are more sub categories and they now all close themselves automatically when they are not needed. The only problem (isn't new) is that choosing a preset doesn't make them close/open.

- Moved the server-side and non-tool specific functions from stool to autorun/server folder.

- Add check for the wheel's unit vector and the suspension's unit vector in case they are same direction but opposite sense. Should probably check if the cross product == 0 instead.
