* Harden the new `hideAllViewsExcept()` to not do erroneous things if called when
the binding is already gone.
* Generalize things into `hideAllViewsExcept(thisOne)`:
- Clear `_viewShowing` in there and do the descriptionHeightWorkaround thing
in there too,
- For Photon panels, do all the 'current' attribute setting in there. To show
a panel during transition, I introduced the 'in-transition' attribute.
* I had to make sure not to over-eagerly dispatch 'ViewShowing' events, because
that confuses some,
* Move the temporary panel handling, which contains an ephemeral panelmultiview
instance, internally. This cleans up the hacky, duplicate PanelUI.js code nicely.
* Keep a local copy of `_transitionDetails` to ensure it's still there after transition,
* Harden `_cleanupTransitionPhase()` to only clear the phase that belongs to a
specific transition, _if_ that's passed in as an argument. This resolves any
potential raciness that might occur when `showSubView()` is called again mid-transition.
* Skip the UITour element visibility check when it's inside a panelview, because
too many things need to happen and that check is too simple to be useful in
that case.

There are no more help/quit buttons in the panel that shows up in customize mode,
and there are no more hyphenation quirks in items in the panel, so those tests
have been removed. The remaining tests are updated to test the correct panels.
