Blitzkrieg 1.9.3

A few fixes before we tackle the next major release.

Fixes

• /stats, /evolution, and /statsfull now properly handle unowned or unplayed tanks

Technical Changes

• Added a Command suffix after all command exports
• Added a Route suffix after all route exports
• Moved tankopedia and tankaverages into a runtime cache
  • But, this time, it's a promise so we get the best of both worlds
