Merge ~kissiel/plainbox:fix-1741109-hide-automated into plainbox:master

[Maciej Kisielewski]

Add 'hide-automated' as a valid option to the 'output' variable in [ui] section in configs/launchers.

This variable is listed on http://checkbox.readthedocs.io/en/latest/launcher-tutorial.html and the code did not actually support it. The logic was there, just the declaration was missing in the config module.

This MR adds this declaration.

To test it use launcher with this section in it:

[ui]
output = hide-automated

It should behave just as 'hide' would.

TBH I don't know why we missed to land this earlier.

Fixes: LP:1741109
