Changes: smash everything back on to master

- Experiments show that the partitionmanager crashes are not new
   or specific to the swap-UI. So reduce the number of open branches
   by merging everything back to master, for a 3.2.4 release once
   the crashes are disabled (and the UI is up-to-snuff).
 - Pull in and document new code from Collabora.
