Add go-bindata reference to README.md

[jayunit100]

After stumbling upon this (former huge user of go-bindata, in fact, I'm the reason its a core dependency of kubernetes), I'd like to suggest we add a reference to this as a replacement for go-bindata to this site. I think alot of folks will benefit from this.

I'm testing it myself now, and I'm an avid buffalo user myself as well.

Thanks !
