Throw down some pins for the map of the run.
Bug fix. Span map properly. Delete runs. Cleanup.

- Made it so runs can at least be deleted from the run page. Swipe to delete would be nice. The icon is pixelated. Not sure how to fix it yet. This is even the case in Xamarin examples.
- Fixed it so it actually adds trip positions to the totalPositionHistory so the run can sort of be mapped. Even if it is with just points.
- Remove now unused test page.
- Make the map span be at a reasonable position to show only the run positions.
