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...
The file downloader was changed from a simple redirect to the file to one
implemented in PHP, which should make it safer, by making it possible disallow
direct access to the file, to prevent executing of atttachments
The filename has a new format:
bin2hex("{$original_name}")."-{$filehash}"
This format should be respected. Notice the dash, which is important to distinguish it from the previous
format, which was "{$hash}.{$ext}"
This change was made to both make the experience more user friendly, by
providing a readable name for files, as opposed to it's hash. This name is taken
from the upload filename, but, clearly, as this wasn't done before, it's
impossible to have a proper name for older files, so those are displayed as
"untitled.{$ext}".
This new name is displayed in the UI, instead of the previous name.
