Previously, on very narrow screens, the album cards were spilling
out of the container. Now they are better contained but I am
still not 100% satisfied with the margins between them.
- album card has placeholder for future thumbnail.
- replaced nested tree hierarchy lists with separate boxes.
- list/grid view also applies to the root listing.
- added a sticky right panel for all the tools. not pretty yet.
- mechanism for adding sticky panel changed. instead of applying
it to the #right, you apply it to #content_body so that its
grid layout can be updated properly.
- common.css, removed html and body margins so that using
full height #content_body will not create a scrollbar.
Simplifies the "fill remaining space" construct I use a lot.
Added more css variables, I'm thinking about future theming.
- photo_card.css, slightly heightened to improve name clipping.
- clipboard.html, added a small screen mode.
- login.html, centered the boxes and fixed message area being
too small due to a previous change.
- search.html, simplified some conditional texts.
