Dashboard Tweaks

References #160 

- Weeklies are ordered by date, so the soonest appear first
- Tables are used instead of unordered lists, and are set to be flush with their container
-  Tweaked some wording to be domain specific. eg. Meetings are Weeklies, events are Workshops. This is only in the view though.
