Add actions to My Projects view

- Moves action item/TODO/etc. forms into seperate template files
- Add some more functionality to the my projects view.
        Adding action items and bugs requires more context data that
        just the PID, so those buttons are a little more complicated to
        add to this view. For now we have TODOs, forum posts, and status
        updates here.
Merge pull request #98 from nikolas/my-project-actions
