This drops fomantic-ui as css toolkit and introduces tailwindcss. With
tailwind there are no predefined components, but it's very easy to
create those. So customizing the look&feel is much simpler, most of
the time no additional css is needed.
This requires a complete rewrite of the markup + styles. Luckily all
logic can be kept as is. The now old ui is not removed, it is still
available by using a request header `Docspell-Ui` with a value of `1`
for the old ui and `2` for the new ui.
Another addition is "dev mode", where docspell serves assets with a
no-cache header, to disable browser caching. This makes developing a
lot easier.
Show also "empty tags", where the count is 0. Before only tags with a
count > 0 were displayed. When searching this is fine, but when using
drag&drop to attach tags to items, it is good to see all. They can be
hidden via a button.
The tags are now ordered by their count descending, but regarding to
the overall count – not the current view. Otherwise the tags are
reordered when clicking on them, which is confusing. Also it then
shows the "more important" (most used) tags first, even when the
result is a subset.
A fix was made related to updating the menu. When coming back from
the detail view where a tag with prior count=0 was associated, the
menu didn't show it, because it relied on a previous state, where this
tag were not included.
The functionality of the search bar is now in the search menu, too.
The search menu shows one input field for "textual search", which is
either the fulltext search (if enabled) or a basic search in various
names.
Now a person that is not marked as "concerning only" is treated as
"correspondent only". The options of all dropdown fields are now
restricted to those subsets.
Issue: #332
The option "contents" has been removed from the search bar. This field
is not intended to be used alone, but rather in conjunction with other
fields. Otherwise it may be really slow on large databases.
The "name" option has been removed from the search menu. This doesn't
provide anything better over the "Names" field, that search more
fields, including item names.
This reduces (unecessary) requests and eases the restless list
rendering. Throttling is still in place to avoid too many requests
when e.g. holding the enter-key.
