Major update: folder hierarchy, version updates, templating structure and more

This is a significant pull request with many updates related to versions of libraries, templates, folder structure and overall usage "readiness".

Twitter Bootstrap is updated to v3 and all other libraries used in the project are updated to their latest versions.
Forms are pre-set by default, everything is linked and all additional stylesheets are in place to kickstart the development as much as possible.

Two sample screenshots are attached so you can see how the boilerplate looks out of the box. You can also run it without any additional configuration necessary for forms.

All commits are kept smaller so it is easier to follow up on what each of them does.

I am aware that this might not align with your direction of the project, but wanted to offer it in case it makes sense for you as well.

Let me know if you have any questions about the updates.

Thanks!
