Hi,

I wanted to merge many of the already open PRs, and make some other changes & fixes, so I forked, cherry-picked the commits in many of the open PRs, and added my changes & fixes.

So merging this PR would merge the following PRs:

315, #313, #312, #307, #289, #278, #270, #208

And add the following fixes & changes:

Bugfix: textfields in Info panel were too long (overlapping their buttons)
Bugfix: completely disable registration, don't just hide the page - Fixes #207
Bugfix: folders thumbnails were squashed because height was different than width
Bugfix: couldn't use the scroll bar in the header zone, because the header element was over it
Bugfix: RSS and menu buttons were too close from the right edges, when a scrollbar is present
Improvement: Made site name (logo) clickable, to go back home (same as 'albums' link in left menu)
Improvement: added some padding at the bottom of the menu, in order to not have anything hidden behind the browser's 'currently selected URL' tooltip
Improvement: Use Escape on keyboard to close the currently open photo

Other users who would want the above PRs in their PhotoShow installation can get the code from https://github.com/gboudreau/PhotoShow/tree/master
