www/rustypaste: Update to 0.8.4
ChangeLog: https://github.com/orhun/rustypaste/blob/v0.8.4/CHANGELOG.md
* Allow downloading files via ?download=true parameter
* If you specify this for a file (e.g. <server_address>/file?download=true),
rustypaste will override the MIME type to application/octet-stream and
this will force your browser to download the file.
* This is useful when e.g. you want to be able to share the link to a file
that would play in the browser (like .mp4) but also share a link that
will auto-download as well.
