* chore: disable deprecation warnings in GTK client
Yes, updating the GTK codebase is still a goal. (help welcomed!)
But there's a deluge of deprecation warnings that drown out other more
important warnings, so turn off deprecation warnings for now.

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.

This file was originally written by Richard Hughes, for Fedora, who
proposed it on the Transmission forum here:
https://forum.transmissionbt.com/viewtopic.php?f=3&t=16443
It's used to display a nice description and screenshot in GNOME
Software. The format is documented here:
https://www.freedesktop.org/software/appstream/docs/chap-Quickstart.html
The <_name/> and <_summary/> fields match the Name= and Comment= fields
in the .desktop file so are already translated.
The screenshot is taken with Transmission 2.92 (14714) on Fedora 25.
It's at one of the sizes recommended by the GNOME Shell Screenshot
Window Sizer extension.
The <update_contact/> is based on the Git history.
