Full Changelog: v1.29.5...v1.29.6-rc.3

Major changes

• Database backend switched from LevelDB to SQLite. There is a migration on first launch which can be lengthy for larger setups. The new database is easier to understand and maintain and, hopefully, less buggy.
• Deleted items are no longer kept forever in the database, instead they are forgotten after six months. If your use case require deletes to take effect after more than a six month delay, set the --db-delete-retention-interval command line option or corresponding environment variable to zero, or a longer time interval of your choosing.
• Modernised command line options parsing. Old single-dash long options are no longer supported, e.g. -home must be given as --home. All serve options are now also accepted as environment variables.
• Rolling hash detection of shifted data is no longer supported as this effectively never helped. Instead, scanning and syncing is faster and more efficient without it.
• A "default folder" is no longer created on first startup.
