Instead of embedding the entire tag list in the search.html template
every single time, this script loads the tags from the new,
cache-enabled endpoint /all_tags.json. Then we can use html5
datalists to create autocomplete forms on the search and photo pages.
I found that the strict heirarchy was not satisfying the situation
where one tag is the intersection of two others, but we can only
pick one as the parent
For example, does red_jacket belong under clothes.red_clothes or
clothes.jackets? A search for "red_clothes AND jackets" might
give us someone wearing red pants and a black jacket, so this
definitely needs to be a separate tag, but picking only one
parent for it is not sufficient. Now, a search for red_clothes
and a search for jackets will both find our red_jacket photo.
The change also applies to Albums because why not, and I'm sure
a similar case can be made.
Unfortunately this means tags no longer have one true qualname.
The concept of qualnames has not been completely phased out but
it's in progress.
This commit is very big because I was not sure for a long time
whether to go through with it, and so much stuff had to change
that I don't want to go back and figure out what could be grouped
together.
It was getting difficult to remember which of the normalizers
use None and which don't. So let's try to be a little more consistent
and just use empty sets, etc, so the caller can rely on receiving a
set instead of having to check for None.
Also renamed search parameter authors->author to be more in line
with the singular form of extension.
Adds CSS variables for the highlight and shadow so they don't need
to be custom-defined for each color of button.
Elements should use more generic classes like green_button instead of
add_tag_button unless there's a good reason.
Appearing on search and album pages, the tray is where you can
remove items from your clipboard without having to click on its
checkbox -- that photo card may not even be on the current page.
New frontends folder will hold all front-end interfaces for etiquette. Existing flask site moved here and refers to itself as a package with external launcher. etiquette_site renamed to etiquette_flask
