IPFS Bootstrap Command 

Resolution to issue #117 

All of the features work as described in the issue referenced.

The peers are added to the config file. Each peer object occupies one line in the config file for simplicity of adding/deleting. This command assumes the bootstrapped peer created in init.go (mars) is constant. You can add new peers, delete those new peers, and list all peers (including mars). 



Remove this method too.
