Tidy up

Removed some redundant code and added some comments
Tidy up
Removed the default route

As we can reuse the home route for this
Added return this to the end of each render
Added bootstrap assets
Completed the nettuts tutorisld
Added new home model to view
Big changes!

Got rid of the lorem ipsum stuff and the template now pulls in actual
data from the model
Content changes
Created new home model

The home page will become more complex in time, so needs a model to keep
control of it!
