fix manual installs using setup.py

[briancappello]

Installing from source wasn't copying the html templates:

$ mkvirtualenv grip
$ workon grip
(grip)$ python setup.py install
(grip)$ grip

Oh man, I broke this. I removed package_data in a cleanup effort.

Pulling this fix in now, but I'll research this weekend which solution is the right one, package_data, data_files, or another approach. Do you have any insight to this?

Thanks for the fix!
