Bug#733860: dependencies

[Jason Hernandez <jason@jasonhernandez.ch>]

It looks like all the dependencies for Pond other than AGL's go-gtk have been packaged. https://github.com/agl/go-gtk 

We have golang-go.crypto-dev

https://packages.debian.org/sid/golang-go.crypto-dev

and golang-ed25519-dev

https://packages.debian.org/sid/golang-ed25519-dev

I made an amateur attempt at packaging AGL's go-gtk (hopefully this helps someone who understands go / packaging better can clean this up)

https://github.com/saltthefries/go-gtk

I'm trying to put together makefiles to create a pond-client package, but creating makefiles for multi-binary go packages is currently beyond my knowledge.
