Refactor storyboard to remove unnecessary navigation controllers

To avoid the need to have many navigation controllers and keep all the
transations between views in the storyboard (as segues); two custom
segues where added:

- **Start Over** allows a view to "reset" the navigation controller stack
and "start over" with a new one as the root view controller

- **Replace** useful for completly removing a view controller from the
navigation controller stack and push a new one, thus, "replacing" the
current vc with the new one
