* Fixed is want to read coming back as a string and not working correctly.

* Changed from to Continue to be more explicit

* Added the first migration which exports data as a csv in temp/. This is the backup in case data is lost in the migration.

* Note for later

* Fixed the migration for the series relation so when deleting any series on any edge of the relationship, the SeriesRelation row deletes.

* Change buttons back to titles on series detail page

* Wrote the code to import relations from the backup.

* Added an additional version check to avoid file io on migration.

* Code cleanup
