add missing templates

trying to fix issues that @jeromecornet indicated here https://github.com/Shopify/huboard/pull/5#issuecomment-51200178

i had some trouble because i did an `npm update ember-tools` on my machine. building the javascript with `ember build` results in incompatible handlebar versions:

```
Uncaught Error: Assertion Failed: `blockHelperMissing` was invoked without a helper name, which is most likely due to a mismatch between the version of Ember.js you're running now and the one used to precompile your templates. Please make sure the version of `ember-handlebars-compiler` you're using is up to date.
```

i tried ALL available npm module versions, but none of them produced compatible results, _yeah_!
 
```
npm install -g ember-tools@0.2.x
```

nevertheless, this take the same approach that @kvs did to fix errors yesterday. looks like there were some more templates missing.
