Install a gem by specifying the git repository URL

[kathgironpe]

Hi. I wonder if you guys considered allowing gems to be installed by specifying git URL or is it possible to do so?

👍 on this one. @cyx are there any plans to support this? I know it's a more complex process than a simple gem install and it will make dep's codebase bigger but it's quite handy when it comes down to testing dependencies before they're published. Thoughts?

@dariocravero cool! 👍 With this merged, I think I can use dep more often. :)
