Scrollable login

I just tried installing SifterReader on my phone and noticed that when I slid out the keyboard to type in the access key, the access key field was hidden from view (landscape, below the screen edge) and I couldn't scroll to bring it into view. This is a fairly straightforward fix - wrapping the existing layout in a ScrollView.
