Add the number of pending updates in the systray applet

[Antiz96]

Depending on how hard it is to handle, having the systray applet showing the number of pending updates (such as what the Arch Updates Indicator Gnome extension is doing) would be a nice plus!

Retrieving this information from the main script and add it to the current_state file (for instance) would be trivial. However, the integration of that information within the systray applet itself needs to be studied.

@trigg Do you mind if I assign you on that issue as well?

No urgency at all though. At this point this is more of a study than an actual feature request.
Actually, if we do not manage to find a simple and elegant way to handle this, I'd rather drop it than making the code unnecessarily more complex just for that. The number of pending updates is already reported in the desktop notification to be fair.

From what I'm seeing the only route to doing this would be to load the icon, and draw into it before sending the altered buffer over dbus.

From what I'm reading there's no promise any particular panel will accept raw-buffer icons.

By all means assign me, I can do some mock ups when I'm available next

Uh, ok. Thanks for the research. We'll see how it goes, but once again, if it is too complicated/hacky/whatever, let's not wrap our head too hard on this :)

I assigned you, thanks!
