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...
