Moved actions (on hover) dropdown to status buttons

Before the dropdown only shows on hover over table row next to the title.
Now it is always visible in the Status column.
This also solves accessibility issues (being able to tab to items, etc).

This only does it in the articles list view. Rest is on its way...
