Fixes config

* Gave you some bad advice about the uglify task. Turns out it's still
used, but the ngmin task swoops in before-hand to overwrite 
generated/app.js with an angular-safe minification, which turns out to
safeguard it against uglify's mangling
* Sets the prefix to "api" since that matches what you have in your
`config/server.js` and seems to be what a lot of folks use.

Unfortunately neither of these seem to be the root of the problem with
the error you encounter in dist/index.html
Fixes the issue mistakenly attributed to uglify.

Turns out the minification issue was not a Lineman configuration problem

After lots of experimentation, we isolated the issue to ngmin's 
inability to recognize that FooController was an angular unit.
Using the more formal declaration and attaching it to the app made
running the app out of dist directory with a static file server work
just fine!
