New Running Services UI.
This introduces a simplified (thanks, dsandler!) UI for Running Services, collapsing the groups of apps and processes into single lines. Tapping on a line moves to a new activity showing details on that group, where the stop functionality is now available. This UI is now also integrated into Manage Applications, as the Running tab. You no longer get a really confusing, misleading, scary list of every package that appears to be laying around for some reason. The code was also re-organized, to put everything related to Manage Applications and Running Services under its own package. There is still some clean-up -- some performance improvements (such as not re-computing the world when we switch to the details view), and if this looks good then eradicating the old running services UI.
