[sugar] 9.1 proposal: View source key everywhere

I think that any activity that goes to the trouble of building their
own view source mechanism can handle the added overhead of adding a
line to the activity.info file. Seems like that is the easiest path.
Doesn't it have any negative repercussions in the long term?
