Invalid tree info when trying to deploy to GitHub Pages.

[brks]

Hi!

I'm attempting to deploy to GitHub Pages using Ship, and It's just throwing an error {"message":"Invalid tree info","documentation_url":"https://developer.github.com/v3/git/trees/#create-a-tree"}

My ship.conf is as follows:

gh-pages:
username: brks
password: ***************
repo: brks/brks.cc

yo yo

if you push a target to gh-pages

git push origin master:gh-pages

and then run ship it will work, this is an issue with the initial branch creation since there is not a tree yet... something we need to fix 🐐 🍕
