Rework net for 0.102
This is a collection of targeted fixes for the %"0.102" release. Most of them are quite narrowly targeted bug fixes. I couldn't avoid reworking the update scheduling in order to fix some of the listed bugs. This is the only part that seems possible to have regressions. In any case, if there are regressions, they will be in a very limited chunk of the code, in `UpdateService`, which we have no plans to touch in %"0.103 - UX Overhaul" so it'll be easy to do a 0.102.1 release.
