Full tile is clickable

So far, you can only jump into bulletin or task details by clicking on the narrow arrow part on the far right of task or bulletin tiles. We changed this approach and made the full tile clickable, thus making it easier to navigate to the detail view. Existing links and functionality on the tile are still supported (e.g. opening the task sub-menu on the bulletin tile) On top of making the full tile clickable, we also make it more visible, which tile is currently hovered over, by adding a light blue outline.
