Add in `.DS_Store` for fools like me
Add in json plugin to requirejs

- Allows us to load in json fixtures using requirejs
- Uses `json` plugin from https://github.com/millermedeiros/requirejs-plugins to load in json
- This has a stupid syntax, but I think it's better than adding a huge object into our tests
Move fixtures to base of app
Add fixtures in as initial dependencies

- In order to pacify both `grunt jasmine` and `grunt jasmine_node` we need to load in our fixtures before running any tests. I couldn't find a way to reliabily load in fixtures at the time of running the test: the environment has to be setup first
- Renames fixtures to something a bit more obvious
- TODO: add global fixtures path?
Just test ten dashboards — we're in sprint mode!
