Datatables implementation along with various changes.

Ok here is the code for the datatables, try to clone it somewhere and run to see how those tables feel, I really really like it ^^

In the index layout pages of the admin pages you have the init code for the datatables. As you can see pretty much everything is left stock. There is a LOT that can be done on the tables by just editing this init and maybe adding more plugins, like the one I added to have the fnReloadAjax function. 

What has changed:

- Bootstrap is now loaded through composer.
- New modal layout in admin views.
- New method in all admin controllers to display ajax data specific to Datatables.
- All index admin views modified for Datatables.
- All other admin views modified to be pop modals.

All of the changes from the pull request [#120](https://github.com/andrew13/Laravel-4-Bootstrap-Starter-Site/pull/120) are included in this one as well.
