Before this commit, 2 usability issues were reported:
1. Some people would get stuck with unpublished content without even knowing it
since they would not understand the page is unpublished.
2. People would have a hard time finding the publish button (small toggle on
the navbar).
Now:
1. We now display a red ribbon on the top right corner specifying the page is
unpublished. Hopefully it can't be missed.
2. This publish button will be more visible for unpublished content since it
will be red (danger) color. Hopefully people will notice it at first look.
Note: It is implemented in a generic way so any 'o_switch' can be turned
into this version by simply adding the 'o_switch_danger' class to it.
