Replace noty by CodeSeven/toastr '2.0.3'

Smaller file than the latest noty, uses classes to set css styles instead
of embedding them in the elements and seems a bit more lightweight but still
doing all we need.

Also made the notifications look better and not close on click, so text can
be copied. They all have a close button though.
Playing with bootstrap's colors, everything less 'bright' now
Better usage of rows and columns for navbar and webconf partial

Use make-row and make-**-column inside the css instead of .row and .col**
in the views.
