Description

I would like to open a repo in another application.

Version

GitHub Desktop version: 0.5.3

OS version: macOS 10.12.4 (16E195)

Steps to Reproduce

1. Click the current repo drop down.
2. Right click on a repo

Expected behaviour:
A contextual menu shows with options to open a repo in Finder, Atom, or external editor (maybe this last part would be supported via a plugin?).

Actual behaviour:
The only option shown is to remove the repo.

Github for Mac currently implements this functionality.
