new: only auto-refresh run page while browser whindow is focused

The refreshing job is still scheduled every 10s but it is stopped when
the browser window loses focus (even when changing to another tab) and
restarts when the browser whindow is focused again.
[WIP] new: provide the framework to be able to update the run page
fix: now is possible to provide all Cloud IDs

Previously it was not possible to add Cloud Ids for new base images,
because only the Cloud IDs already present in the image configuration
where taken into account for display and edit.
change: only flash updated nodes when html() is different

I.e. if we 'updateWith' a new jQuery element with only differs with the
attributes but not the inner HTML, we do not have to visually highlight
the change, since nothing will effectivelly change in the UI. Only
things like the tooltip (attr 'title') might have changed.
change: make muted text a bit lighter
change: display :cell/text tooltips as Bootstrap tooltips

E.g. the relative time in a :cell/timestamp, because it uses :cell/text
in the background, or a :cell/enum in view mode.
change: make image-build/image-run/deployment-run consistent
