Improve Projects page navigation

[mjherzog]

When working with a large number of Scan projects it is painful to navigate on the Projects screen because the only page navigation is at the bottom. It would be nice to use the page navigation approach from DejaCode where there is a Page x of y box at the top and bottom of the screen and you can also use the left/right arrow buttons, but the Page x of y navigation available on the SCIO detail screens (Packages, Dependencies, Resources and Messages would be useful.
