ui: add util for fragment objects
Add a utility to easily work with lifecycle-dependent fragment objects.

This reduces the code duplication required to maintain objects that
would leak after the destruction of a fragment. We normally would not
do this as a delegate, as that usually entails some lifecycle wizardry
that can easily break and crash the app in esoteric situations.
However, this this just extends the normal lifecycle without watching
any state, it seems to be pretty safe to use.
