Update go-random to the latest commit

[chriscool]

As some bugs were fixed in go-random, maybe we should update it in Godeps/_workspace/src/github.com/jbenet/go-random.

I am not sure I know how to do it properly. Is there a go command to do that?

Perhaps there is a more straightforward way to accomplish this, but this is the procedure I used to update go-random:

cd go-ipfs
godep update github.com/jbenet/go-random

And to update all dependencies:

cd go-ipfs
godep update ...

NB: Not ./... but ...

Thanks @maybebtc! I sent PR #295 so that the go-random update doesn't break the tests.

I'll close this issue as the concern is represented in PR #294
