Blitzkrieg 1.4.0

A few features :star: and a few much needed fixes :wrench:!

Changes

• Added an "today" row to /today which displays your overall statistics
• Gave /tankstats the new blitzkrieg look
  • Also added "today", "60 days", and "career" stats
• Added a beta warning to generated images
• Updated the logo for match the new slate theme
  • Canary versions now use the canary logo variant
• Added subtle polka dots to the background

Fixes

• Rewrote /stats to precisely calculate stats on a per-tank basis
  • This should stop the bot from hallucinating about stats
  • This should also stop the bot from giving stats from like a week ago
  • Also added "60 day" stats
• Tank autocomplete is now more human-tolerant just like username autocomplete
• Titlebar discriminators are now truncated on overflow

Technical Changes

• The bot now uses bepaint, a library that I made that standardizes the color palette
  • Also updated the logo to follow this
• Optimized how fonts are imported by fetching them all asynchronously
