I spent many hours testing this version, but as usual, make backups just in case.

Fixes:

• Fixed the task manager, preventing issues with slow operations in specific cases (like a duplicate paste ending early)
• Fixed structure (tree) growth not listened to for WatchDogRegion rollback.

Changes:

• 3.6.0 specific: Updated mappings to 1.17.1. Which exclusively affects the grass path block rename.
• Allow updating/re-saving regions (arenas) that were previously saved. (this was a requested feature)

Other changes:

• Moved code to GitHub and split it into two repositories: one for the new version, and one for the legacy version.
• Added project to JitPack for maven for developers.
