* Flatten karts as if they were hit by a swatter
* Block most of the view with plungers

* Use a thin black border for the font, and make the font white-colored
* Decrease the font scaling to 0.7, so that other UI elements can be seen more easily

Most shortcuts are now handled by Debug instead of InputManager directly
Other changes include:

* Change the 1st-person view shortcuts to work more like in Blender
* Add more keyboard shortcuts for quickly seeing the top and sides of a kart

* Improve the debug menu, various fixes to some menu items, and mouse-accessible actions
Includes:
* Debug menu opens at the cursor position, but not at off-screen places
* Ensure that the debug menu stays (almost) within the actual window
* Middle mouse button can also be used to access the debug menu

* Add ability to set powerup and nitro amount by debug slider dialog
* Label the some commands with the new keyboard shortcuts
* Screenshots can now be saved via the debug menu

* Replace the 10th kart camera target with the last kart camera target
* Switch the shortcuts used for activating history save and manual replay saving
* Finish labelling the remaining debug actions, complete the debug keys help dialog
Unfortunately, the now unused tutorial message dialog has been repurposed for this use,
and the font sizes greater than 'Large' will cause some text to draw outside the dialog
* Document the remaining command-line parameters, clean up some of them
This adds another method that will print out the previously undocumented debug options
Rename --gamepad-visuali[s,z]ation to --gamepad-visuals
Also fix some comments related to the user config, including the game mode numbers
* The AI cannot handle the anvil powerup anymore, but it won't spam logs anymore
