[WIP] Feature/bower process

So I've gone through the apigility project and have made changes to the build/development process to make things easier, automated. (The base coming from generator-angular that I frequently use).

JS/CSS are declared and processed using grunt-contrib-usemin inside index.html, as shown on IRC earlier. Getting this to work was a bit of a nightmare due to the AssetManager and Grunt not talking about directories from the same relative point. I've fixed this by altering app.phtml but it's not a clean solution right now.

I've moved vendor inside /src as it should only really be through development. It all gets minified and shoved into /dist upon build. I also added a vendor.less so you can import other libraries like Bootstrap and alter variables like brand-primary/brand-success as I've added as an example.

The whole thing works, you work with the /src version of the project with "grunt serve" which will create a livereload listener and start watching for changes. You can listen to livereload with something like: https://chrome.google.com/webstore/detail/livereload/jnihajbhpnppcggbcgedagnkighmdlei

When you're ready to create a build, you just "grunt build" or if you want to include jshint and tests as well: "grunt"'. I've added additional jshint rules and then eased them as it failed miserably. The unit tests is also something I need to check as I just copied the same structure from another project of mine but not tried them yet.

I've removed the need to manually specify your dependencies into services as string as ng-min will sort that out automatically, like so:

```js
// Can use this
angular.module('ag-admin').factory('AuthenticationRepository', function ($http, $q, apiBasePath) {});
// Instead of
angular.module('ag-admin').factory('AuthenticationRepository', ['$http', '$q', 'apiBasePath', function ($http, $q, apiBasePath) {}]);
```

Right now it seems ng-min is having issues processing `_declarations.js` as there are references to Services which aren't injected in. These guys say they should be moved to a service and injected in to rectify it: https://github.com/btford/ngmin/issues/23

If you want to check it out, change $version to 'src' inside `app.phtml` and `"grunt serve"`. See what you think.
