Merge e273c0d73f into fce0398470

The Content-Disposition header was set to 'filename="name.ext"' without
a disposition type, violating RFC 2183. This caused third-party HTTP
clients (e.g. Go's mime.ParseMediaType) to fail parsing the filename.

Added 'inline;' disposition type prefix to all Content-Disposition headers
in the /view endpoint.

Fixes #8914
