Kepler 21530 Controller / Deck Update

The default branch has now been updated to the Kepler 21530 build. The main goal of this build was to prepare the game for Steam Deck verification, although there are a few minor gameplay improvements as well:

Deck/Controller Improvements:

• Improved Save & Load menus to enable all functionality via controller inputs, including toggling selections for delete, deleting old autosaves, etc.
  
• When text scaling is set to maximum (set by default on the Deck) all text should be a minimum of 9 pixels high at 1280x800 resolution.
  
• Eliminated areas where scaled text overlaps other UI elements
  
• Dropdowns now keep current selection in view when using controller
  
• All text input fields should bring up the virtual keyboard on the Deck
  
• Now possible to toggle highlight, fog in map mode
  
• Research panel correctly keeps research selection in view
  
• In cases where there are two scrollviews visible (such as the ship log), right stick scrolls the first, dpad scrolls the second.
  
• Cargo screen allows for quickly analyzing items and proceeding to the next
  
• Improved input handling in the shipyard
  
• Chromaplate swatch customization now works with controller
  
• Crew help should correctly reference controller inputs instead of keyboard if the controller is being used
  

General fixes:

• If the player has set a "design goal", the trade screen previously did not show shortfalls in the faction's own reserve currency. Now it does.
  
• Rendering optimization when in map mode
  
• Several minor typos
