fixed test
fixed [%s] bug
this warning should only print out on debug

(perhaps should be logged instead)
uncommenting global debug

let's keep this a turn-on for testing sort of thing.
(want the outputs of commands like `ipfs add` to be
usable as inputs to other programs/scripts).

maybe we should consider adding a --debug (not -d),
once we figure out adding flags that apply globally :)
@whyrusleeping
ipfs add should output hash to user

for now, ipfs add output format:

    added <hash> <path>
    ...

(these commands will adhere to strict formats.)
added mars.i.ipfs.io as a bootstrap node

In the future, let's have a (signed) list of bootstrap
nodes. Ideally just a list of ipfs multiaddrs (with node.ID)
output + linting
