colorful theme has been default theme for awhile. having colorful theme
try and grab icons from other theme doesn't work on Linux.
Also adding two additional icons, info is to hint to the user that they
should hit verify after pasting in a token, sync is to show that the
verification is occurring.
I've seen some comments stating that sharing pre-compiled packages
of yuzu is problematic for linux distributions due to some contents
having license of CC BY-ND 3.0
Better licensed sources of icons have been found for most cases,
see the changes to the .reuse/dep5 file for details.
Placeholders for connected/disconnected icons
At the time of writing I consider these icons to be placeholders,
hence three copies. colorful is grey, default is black, qdarkstyle is white
connected is gnome/16x16/network-idle.png with no changes
connected_notification is gnome/16x16/network-error.png with changes
disconnected is gnome/16x16/network-offline.png with changes
Looking at licenses: GNOME icon theme is distributed under the terms of either
GNU LGPL v.3 or Creative Commons BY-SA 3.0 license.
Debian appears to explicitly state they're licensing under
Creative Commons Attribution-Share Alike 3.0
From a tarball at the following link suggests we can just attribute GNOME Project
https://download.gnome.org/sources/gnome-icon-theme/
When attributing the artwork, using "GNOME Project" is enough.
Please link to http://www.gnome.org where available.
