Fix a few more bugs and updated the KiriKiri plugin.

Full Changelog: v3.29.6...v3.29.7

Fixes for load_backup:

• The intermediary file backup.tmp.file.json was left on disk after loading the backup.
• A typo caused the current strings.json to be lost during the renaming of the backups (in theory at least, it never happened to me despite using it often and I can't explain why).
• Switched from using copyfile to delete and move instead, to reduce the amount of writing.
