Name conflict with GitHub's hub CLI tool

[rkalis]

GitHub has a CLI tool called hub that wraps git with some GitHub specific functionality. It's fine for me to rename textile's hub binary to textile-hub and manually adding it to my path, but it is a bit of an annoyance. Just want to make sure you guys are aware of it, but feel free to close the issue if you don't think it needs to be changed.

i saw this a while back... i also saw gh so wasn't sure which they had intended to maintain. it's tricky to pick a simple, fully distinct 3 letter bin name now'days so probably fine to keep it for the time-being.
