GitGutter: Unable to locate module [jinja2]

Hey JD,

love your work on this plugin - one of my “must haves” when using ST3.

But have noted since release https://github.com/jisaacks/GitGutter/commit/2cc9a1a9e780e9280480c6c17d80c214af5c1245 I’m getting a Python module error as follows:

ImportError: No module named 'jinja2'

Have tried pip install jinja2 without success too.

Rolling back to a prior commit, e.g. https://github.com/jisaacks/GitGutter/commit/730356dc7aea280e45f0e06e9fe638671e469097 - everything springs back to life.

OS is OS X - 10.11.6

Thanks
