Accumulated cruft data

[nathanw]

I felt like DomoPad had been kind of slow lately, but there's enough else going on with my phone that I didn't worry about it too much.
However, today I saw that the app was using about 1.7GB of storage - pretty crazy for a 60MB app. So I cleared the storage and set it up again, and now it's much zippier.

So there's some kind of storage leak, and whatever is leaking is also making things kind of slow.
