mobile: add option to merge local cloud cache data

The UI is ugly, and of course this is hidden in the developer options that have
to first be enabled in the advanced settings. As I mentioned in the previous
commit, I believe the actual risk that something gets damaged here is very low,
but still, explaining this so it makes sense to the casual user may be a bit...
difficult.
