Patch notes - incl key remapping, change to fire mechanics, etc

Biggest thing is the key mapping menu has finally made it in. (Look for it in the settings menu.)

Also important is that fire, instead of dealing 1 damage directly every tick, now applies a short term debuff 'burning' which deals 1 damage per two ticks but takes time to expire and can be refreshed by new fire. Burning goblins can also spread fire if they walk into dry grass.

• Keymap menu available within the Settings menu.
  
• Previous/next map buttons are now by default assigned to the shoulder buttons on gamepad (rather than dpad L/R).
  
• Fire now applies a 'Burning' damage-over-time debuff rather than dealing damage directly.
  
• Pit Fiend 'Marked' will forcibly trigger the 'Burning' debuff on hit even if the afflicted goblin is in non-burnable terrain. (Used to add heat to the simulation, but the ground would often not catch fire so it felt ineffective.)
  
• Added a 'no mouse' keyboard input scheme (not ideal as is but it's a start). Using 'move' buttons in some menus or 'rotate' buttons in the overworld (i.e. things that you would otherwise use your mouse for) will cause the game to switch to joystick-like controls for menu navigation even when not using a joystick.
  
• 'Regen' now lasts 720 ticks (up from 480).
  
• Bog body attack now applies poison.
  
• Bog body base health increased from 25 --> 30.
  
• Possible fix to the headbanging bug. 🤞
  
• Fixed a bug causing Spellswords to revert to their feral bodies on death.
  
• Fixed a bug causing bosses to explode on death.
  
• Various 'press x' type displays will now attempt to auto-update and display whatever your current keybind is for that button.
  
• Tweaks to behavior of combat radial action menu that allows left stick to be used the way dpad is used to navigate (i.e. tapping left/right to move through actions if you mis-select with your first radial direction).
  
• Fixed a bug that was causing feral teams to occasionally be only 2 goblins even at mid or high levels.
