Dashboard (listing) styles

- bootstrap class=table has to much css weight on children,
   removed table class and added base-styles to
   dashboardlisting th/td.
- button btn-sm used wrong font
- excerpt height converted to max-height to...
- td vertical-align top
- set some (base) line-heights on td
