Seven Kingdoms v2.15.1

Here is a release to help address currently known desync and platform issues. This hopefully will improve stability some. But this is only a start. Likely other big issues remain.

Summary of changes from 2.15.0 to 2.15.1

• Fixed desync on mobilizing workers.
• Fixed desync on troop sortie, by making troop sorting deterministic.
• Fixed desync on AI attack planning, by making AI fort sorting deterministic.
• Fixed error that caused multiplayer save files appear out of sync.
• Changed the Button class to not block on holding down the mouse button,
  smoothing multiplayer games when alot of clicking may be happening.

  fired back to their home town.

  workers.
• Prefer IPv4 addressing for 7kfans.com match-making.
• Fixed ambiguity in some translations.
• Repack structures for Crc checking due to pointer sizing.

• Uppercased the data and user files, as they are supported in the code,
  maintaining consistency and without needing to guess case.
• Fixed missing Fryhtan encyclopedia picture on some systems.
• Fixed observation mode visibility when playing a replay.
• Added support for center and right paragraph justification.
• Packagers please note that the music files must be in upper-case now, see
  the latest download for the music.
