[sugar] Clipboard errata (patches)

OK, I've pushed all of the patches except for "Add descriptions to
clippings", which I want to think through carefully before
resubmitting.  The changes pushed take into account the suggestions
here and discussed in IRC, where Tomeu unofficially r-plussed them.

I'll take a closer look into adding descriptions tomorrow; Tomeu's
effort in this area is already in master, so a very close
approximation of the final behavior can already be seen.
