* Added Dynamic Gravity Toggle
Added an editor toggle for dynamic gravity so users don't need to uncomment code in character.gd.
* Refactor controls export variables
Changed controls export variables to be a single dictionary so they can be edited completely in the editor without having to open the script. I also refactored the controller support section to allow similar functionality for controller specific controls and removed the need to uncomment/comment out lines of code to turn on/off controller support.
* Add more editor descriptions and implement camera axis inversion options
Added/tweaked export variable descriptions so everything has one. Also slightly refactored the camera input inversion code and added the ability to invert the camera x axis.
* Added direction based landing animations
Added some logic to determine which landing animation to play so it's not random anymore. Also added a land_center animation for the case of neutral landings. This can be expanded if desired, but it's pretty convincing as is and is ulitmately a small detail.
* Correct various grammar and spelling errors
A final pass to clean up any grammatical or spelling errors in the comments
* Re-organized Character.gd
Hope I'm not overstepping here, but I re-organized Character.gd to make it a bit easier to read and work with. Added editor bookmarks and collapsible code regions. It's hard to parse in the diff so I recommend you look at it in Godot proper.
* Commented out debug print statement
I assume this was left uncommented by mistake. I was wondering what was printing that to my console.
* Fixed Landing Animation Logic
I guess I was up too late on my first attempt because it straight up didn't work. This new version works as far as my testing can tell.
* Removed some unused variables
base_speed is assigned to speed before the default is updated to what is set in the export variable causing it to be the incorrect value. Calling enter_normal_state() on ready sets speed to the correct value before the player gains control. From my testing, this has no side effects.
