* feat(responsive-ui): Keep aspect ratio for filmstrip self view on mobile web
Right now filmstrip displays self view in landscape mode.
With these changes the aspect ratio of the self view will be maintained
so on portrait mode the thumbnail will be displayed vertically.
Of course this makes sense only on mobile web.

* Fix height
* Enforce fixed column number at various width breakpoints.
