Write-up bittorrent seed node

[kylemanna]

The kylemanna/bitcoin image has everything in it act as a bittorrent seed node. Need to find time to write it up.

Thoughts:

• Separate running docker container (one container for bitcoind, one for aria2 seeder)
• Would clean-up old stale bootstrap file by relocating it and using it to seed
• Write-up howto and place in docs folder
• Add seeder.init script for those on Ubuntu VMs that want to seed

Please don't. This is bloating it up. Write a second docker image that expects a bitcoind container to be linked. If you were using env variables for setting rpc password and username the other container could even pull that from the linked container if I am not mistaken.

Alot has changed in 6 months. No point in doing pointless work.
