Add RPCUseHostWhitelist (maps to rpc-host-whitelist-enabled) and
RPCHostWhitelist (maps to rpc-host-whitelist) keys loading from the plist
to allow adjustment via `defaults` command.
The -symbolic icon variant (if available) is used in the GNOME top bar,
and when the high contrast theme is in use. This icon was created by
Jakub Steiner, and comes from the gnome-icons repository:
https://github.com/gnome-design-team/gnome-icons/blob/master/apps-symbolic/Adwaita/scalable/apps/transmission-symbolic.svghttps://bugzilla.redhat.com/show_bug.cgi?id=1221292
There is some confusion over whether symbolic app icons should be
installed to icons/hicolor/scalable/apps (alongside the regular scalable
icon) or to icons/hicolor/symbolic/apps. On the one hand,
https://wiki.gnome.org/Initiatives/GnomeGoals/HighContrastAppIcons has
this to say:
> […] obtain a suitable symbolic style icon […] and install it to the
> hicolor prefix, the same way you would for the full color variant.
>
> cp myapp-symbolic.svg /usr/share/icons/hicolor/scalable/apps/myapp-symbolic.svg
On the other hand, the Fedora package at
https://src.fedoraproject.org/rpms/transmission/blob/master/f/transmission.spec
ships this icon in icons/hicolor/symbolic/apps:
> # Install the symbolic icon
> mkdir -p %{buildroot}%{_datadir}/icons/hicolor/symbolic/apps
> cp %{SOURCE1} %{buildroot}%{_datadir}/icons/hicolor/symbolic/apps/transmission-symbolic.svg
Anecdotally, icons in scalable/ have minimum size 64×64 on openSUSE, so
symbolic/ is the safer location (given the GNOME top bar uses 32×32
icons). This has the advantage of matching the location used in the
distribution which already ships this file.

Walk up one level at a time until the directory creation succeeds, then go
back down one level at a time. This reduces the number of operations in the
most common case (when directory already exists).
The current icons are very hard to read at the current font size and it's not immediately visible which icon i which.
Additionally, spaces after icons are removed because upload icon is equally positioned between DL/UL speeds (like so `↓ 273 kB/s **↑** 0 kB/s`) which requires reading the whole line to make sense of which number the arrow applies to.
To further separate one type of information from another the hyphen is replaced by the slightly wider en dash.
