A large patch with several improvements for vdiplomacy

[diptobi1]

InteractiveMap:

• added missing CoastConvoyCode in some variants
• added support for terrType Strait

variant fixes:

• fixed borders in Divided States and AgeOfPericles
• fixed dev map not appearing for 1900 variant
• fixed and improved FoW variants:

  • fixed an issue introduced with webdip's anon changes that revealed order status in anon FoW games
  • completely fixed order bar revealing information about SC count
  • added order log history as addition to map history
  • added Preview function
  • synchronized FoW code in all variants (and specifically added missing files in RatWars)

Convoy code:

• fixed two bugs

General:

• overworked Alex DATC changes for 1900 to include the possibility for customizable variant specific test cases (used for Colonial changes; this might be a huge help for fixing variants with complex adjudicator modifications in general)

Colonial Variant changes:

• overworked TSR rules for a slightly different interpretation of the original ones to make them more comprehensible
• overworked rules text to make the rules more comprehensible
• overworked TSR appearance to make the map more readable
• added test cases to guarantee correct adjudication, even in corner cases
• fixed adjudication errors
