New toggle buttons to filter articles (was: Delete favorite button)

I extract drop-down menu actions to make them as button action in the page header.
I removed the favorite button on the category list because it is a duplicate from the button action.
Now button action act as filters and you can combine them.

It is a test to see if we can keep it like that. There is still work to do to extract other actions from the drop-down list.
I did not want to change everything if we don't keep it.
