Integration tests for buffalo plugins, examples, etc…

[markbates]

There needs to be a set of integration tests that, at the very least, run he tests for all “gobuffalo” packages, including example apps like toodo, and plugins such as buffalo-auth.

A bonus feature would be to run some integration tests with some of these packages and examples.

These integration tests should, at the very least, be run on release, but it would be great to get Travis doing them.

@markbates I'm fairly new Go, but I'd like to start contributing because I like your project. This issue seems like it might be something I could handle. Can you elaborate on what the solution might look like? Would it be like a command line program that wraps go test for all (or optionally a subset) of packages, or something like that?
