Fix upload limits and disable color logs

The limits for uploading files were to small in regards to the allowed
maximum filesize of the Bitwarden clients including the web-vault.
Changed both `data-form` (used for Send) and `file` (used for
attachments) to be 525MB, this is the same size we already check our selfs.

Also changed the `json` limit to be 20MB, this should allow very large
imports with 4000/5000+ items depending on if there are large notes or not.

And, also disabled Rocket from outputting colors, these colors were also
send to the log files and syslog. I think this changed in Rocket 0.5rc
somewhere, need to look a bit further into that maybe.
