* Add readme with light setup instructions; tweak ui
These are very minor changes that cover a few issues:
- WebUI Peer list too narrow #4209
On very small screens (for-phone-only), we modify width on some fields for less overlap. But we also truncate using `text-overflow: ellipsis` and `overflow-x: hidden`.
- properly style up/down speed icons
Moved SVG contents into index.html so we can make these style changes based on the `prefers-color-scheme` media query.
I also set a min-width, text-align: right on the download/upload label so they aren't shifting when going from 1 kB/s to 800 Mb/s.
- Add README for `web` directory
It made sense to add some super simple getting-started instructions for the directory.
- Limit input width in Add dialog of Web #5639
Add a width to the open-torrent file input, but also increase the modal dialog container size.
* Add bookmarklet for anonymizing screenshots
I see a lot of blurring going on in screenshots for issues and PRs, so this is a quick little bookmarklet trick to add lorem ipsum text to torrent-names.
`tr_parseNum<>()` is implemented with `fast_float::from_chars()`, and
the latter is documented as "expecting a locale-indepent format
equivalent to what is used by std::strtod in the default ("C") locale".
To accomodate locale independent number parsing, switch back to
locale-independent number formatting in `tr_truncd()` by both removing a
`L` format specifier from `fmt::format_to_n()` call and using a fixed
"." decimal separator when truncating the value.
* Use user-preferred locale
Previous fix adding `L` format specifier was correct but only fixed half
of the problem, as C++ locale is set up to be "C" by default. GTK client
used to call `setlocale(LC_ALL, "")` to set up user-preferred locale
which only affected C functions and `std::locale` (used by libfmt) was
unaware of those changes.
Apply the fix to all the binaries since they're all doing some sort of
output to the user and calling libtransmission helpers, as well as using
libfmt directly.
* Improve libtransmission's json-test
Set the locale C++ way to avoid any sort of inconsistencies, and also
restore it to the old one once finished testing.
* Improve transmission-show test runner script
Quote outputs to avoid CMake error about `message()` being called with
no arguments. Capture stderr to the same output file. Fallback to `git
diff` if `diff` wasn't found. A few other minor changes.
