Improvements to Create Game Menu

Many improvements were made to this menu and the custom game setup process:

• Details are now shown in the right-hand panel for the selected setting
  
• Clicking the Edit button lets you edit the selected file or preset setting
  
• Clicking the Load button lets you load a new file or preset setting
  
• Map Generation settings (such as Starting Biome, Map Size, Resources, etc) can now be loaded as a file or preset independently of other settings
  
• Numeric values in the Create Game Menu screen are validated to conform to specific ranges, and the text field updates with the validated value
  
• Trading Posts now spawn based on a % probability per chunk, not a fixed amount per map. This fixes the issue where trading posts were always limited on an infinite map. Legacy infinite maps will have a % Trading Post spawn probability assigned based on the previous fixed ‘number of trading posts’ parameter
  
• Starting Territory setting is no longer a giant list of chunk coordinates, but a simple area selector (4 chunks, 16 chunks, 36 chunks, etc.)
  
• Can now duplicate and edit Biomes by right-clicking on them. This replaces the misleading 'Edit Map' button that only edited the starting biome
  
• Added new ‘Flat’ preset for Starting Map setting, which is almost entirely level except for lakes
  
• Fixed outer edge water tiles not displaying on large map previews
  
• Fixed large maps having odd square corners where they should be rounded
  
• Non-infinite maps have all terrain tiles visible, even if distant from purchased chunks. Resources are still invisible though
  
• Fixed odd square edges on terrain texturing & improved biome blending generally (in newly created maps)
  

Misc Improvements

• Alert bubbles over buildings and workers will not block cursor when performing an action like building or deleting
  
• Made camera movement less restrictive over unpurchased terrain
  

Bug Fixes

• Fixed Required Worker Count being unable to successfully edit in Victory Conditions
  
• Fixed Required Worker Count not displaying correctly on Victory Conditions panel
  
• Fixed Right-click popup menu would not dismiss if you clicked outside the popup menu, but over some other menu element
  
• Fixed Map Editor screen not enforcing camera bounds
