Media uploads
Fixes #50 (closed)
Enables media uploads via IPFS and S3. User can specify DITTO_UPLOADER='ipfs' or DITTO_UPLOADER='s3'
With the IPFS uploader, IPFS just needs to be installed locally on the machine. You would also proxy_pass media.yoursite.tld to the IPFS gateway on port 8080.
If you choose the S3 uploader, it will still generate an IPFS cid for your files and host them at /ipfs/<cid> for future upgrade capabilities and to benefit from IPFS features.
