Dear Maintainer,

The actions panel has a suspend action but the icon does not exist:

The icon is set in plugins/actions/actions.c - the other actions all
have corresponding icons and suspend is set to system-suspend.png but
that icon does not exist.

eg. lock-screen icon is set to "system-lock-screen" which corresponds to
/usr/share/icons/HighContrast/scalable/actions/system-lock-screen.svg or
/usr/share/icons/Tango/16x16/actions/system-lock-screen.png

But suspend icon is set to "system-suspend" and there is no
/usr/share/icons/.../system-suspend.png

There is an icon /usr/share/icons/hicolor/48x48/apps/xfsm-suspend.png
which looks like it could be used?
