In this iteration we added support for moving the activity bar location to the bottom. While doing so we also made changes to the way the activity bar is rendered when placed at the top.

Testing:

1. Open both primary and secondary side bar and make sure there is at least 1 view open in each.
2. Set workbench.activityBar.location: "bottom"
3. The activity bar should be moved to the bottom of both side bars
4. Interact with the activity bar to make sure it works: Open different views and reorder them with drag and drop
5. Make sure in the secondary side bar that there is a close button at the top right corner.
6. Set workbench.activityBar.location: "top"
7. The activity bar is now moved to the top of the side bar, above the title of the view/container.
8. Interact with the activity bar to make sure it works: Open different views and reorder them with drag and drop
9. Make sure in the secondary side bar that there is a close button at the top right corner.
