small preview on the coming components refactor

[Marco Martin]

Hi all,

here is a small video of a little feature of the upcoming refactor.
The idea for this was given when looking about controls, action buttons and 
screen real estate.

It's basically a title that lives on top of the application page that serves 
as the double service of being at the same time a title for the current page 
and a breadcrumb for "where you are" to quickly go back to the beginning if 
one is pretty deep in sub-sub pages.

In order to save screen real estate, it behaves like a web browser addressbar: 
by scrolling up and down it will show it (eventually making it bigger or 
smaller, controllable via API) or even completely hide it by scrolling down

All the pages will manage scrolling by themselves (unless told not to), so 
will leave proper margins on bottom, so all the contents can go out of the way 
of eventual Action button, and drawer handles (made them in usual hamburger 
and kebab for now, for familiarity)
