feat(gen): Support for server rendering and Angular's HTML5 mode

Server now uses EJS rendering to serve html views. New structure should allow Jade support later on. Additionally, HTML5 mode is now supported. All un-specified server routes now redirect to index so the angular routing system handles them.

BREAKING CHANGE:

angular-fullstack:route and angular-fullstack:view  will now generate views and routes in the views/partials folder.

For existing projects:

Please install generator-angular and use it's subgenerators for creating routes and views. They are exactly the same as the generators that you have been using. Example usage: yo angular:route helloworld.

For New projects:

Continue to use angular-fullstack route and view subgenerators.

The reason for this change in folder structure was to support server page rendering.

Closes #18, #17
