[StoreRemoteMedia] Upgrade plugin to use the new Media system
API Changes:
- Added getters to File to better formalize the ideas of the commit "[Media] Fix issues with database file storage"
UI Changes:
- Now presented thumbnails are actual thumbnails (bug fix)
- Attachment actions have a slightly more extended behaviour
Many other minor bug fixes...
Fixed file quota as well.
There can be more than one file for the same filehash IF the url are different.
Possible states:
- A file with no url and with filename is a local file.
- A file with an url but no filename is a remote file that wasn't fetched,
not even the thumbnail.
- A file with an url and filename is a fetched remote file (maybe just a
thumbnail of it).
- A file with no filename nor url is a redirect.
Routes:
Given these states, updated routes so that an attachment can only be
retrieved by id and a file by filehash.
Major API changes:
File::getByHash now returns a yield of files
Major UI changes:
- Now remote non stored files are presented.
- /view became preferred
- Redirects to remote originals are preferred.
Many other minor bug fixes...
