Remove old releases without requiring a restart

[SpaceviewMob]

We can't assume that our users will restart our app, even for several update cycles. Given that our app contains a few large video files, if cleanup does not occur occasionally, the app size can bloat significantly with duplicate files and old releases that will never be looked at again.

Locally, I've mitigated this by exposing a JS function that removes the unused releases, but it seems like it would be better to happen automatically.

Agreed. Will make it to trigger cleanup automatically after installing the new update.

Just tested this - works perfectly.
