rev update and de string fix
provide nav_min_opacity which allows the navbar to fade or even vanish until hovered with a value of for instance '0';
add sloppy photo setting and fix default navbar hide setting
fix the saved search term delete icons in redbasic so they are hidden by default. This is a bit harder using font-based icons than it was with images that could easily be hidden. We'll do it with opacity instead of visibility or display css settings.
make date order the default for the directory
hmmph. That's why the sort order didn't change...
add attach_mkdir()
private tagged posts weren't creating second delivery chain - they were incorrectly being marked as "in a reshare" due to being obscured.
tag notifications for private posts contain obscured data - they should be blank
solid progress on attach_mkdir - but we need to figure out where to store default file permissions. This should be separate from post/item permissions and we won't be able to set permissions from the DAV interface so if we want something private we have to provide these permissions in our preferences.
make the storage permissions tweakable for hosted environments where they may require tweaking.
don't store update records if we're not a directory server of some kind
