* fixed attachment statistics for sqlite * Split attachment path into internal and external path, so the external source URL can be retained after a file is downloaded * Make internal and external path for attachments nullable, to make clear that they have no internal or external path * Added migrations for nullable columns for postgres and mysql * Added migration for nullable internal and external pathes for sqlite * Added translations * Fixed upload error * Restrict length of filename badge in attachment edit view * Improved margins with badges in attachment edit * Added a link to view external version from attachment edit * Let media_url stay in API attachments responses for backward compatibility --------- Co-authored-by: jona <a@b.c> Co-authored-by: Jan Böhmer <mail@jan-boehmer.de>
