Release 93 - Small patch

Changes:

• Added a save game backup systems. On load the save game directory is zipped and backed up. Up to 5 backups are stored. You can open the backup folder via a button in the save slot screen. This is only intended for calamities, there is no built-in restore function.
• The tech tree now has a "Respecialize" button that locks all parts and gives you all tech points back.
• Minibosses now again have a tech reward (via a dialog).
• Added Phoenix Union Territory Controller miniboss (which had a small update as well).
• Added fallback mission victory detection for when victory event did not fire properly.
• UI scaling is now set automatically on first run based on known display pixel density.
• Moved energy stats up in editor sidebar to always be visible in smaller screens.

Bugfixes:

• "Abandoned" stash encounter let almost infinite number of reinforcements spawn.
• A hangar part stored design was used even if it exceeded the hangar definition cost_limit, max_length, or max_width.
• Rewind to arrival made wormholes disappear.
• Rewind to arrival did not rewind several resources and unlocks properly.
