Trim is here, along with many other minor changes!

Changelog
- Added a chunky trim command which works similarly to WorldBorder's, removing all chunks outside of the selection.
- Added per-command permissions chunky.command.<name>. The old permissions still exist, but will not give access to trim.
- Updated BlueMap integration. Requires further setup with ChunkyBorder + BlueMap to use.
- Updated how command confirmations work. They are now per-user, and expire after one minute.
- Updated community provided Crowdin translations.
- Replaced oval shape type with ellipse. Only the name changed; existing tasks will be automatically updated.
- Fixed issue with continue-on-restart not working for worlds loaded by other plugins like Multiverse.
- Fixed bound checking for square shape. It will no longer generate a rectangle if given two radii.
- Fixed triangle shape only generating if centered at spawn.
