Fix icon order in Systray

[elParaguayo]

To prevent icon order changing after restart/reloading config, icons are now ordered by application name.

It might be a bit nicer to order them at the type level so that the sorting doesn't need to happen upon every draw. I see the wids used for keys in self.icons aren't all that useful; they can be accessed at icon.wid (or icon.window.wid) during finalize(). Then the keys can be the window names, which would be used for ordering in an OrderedDict IIRC.

OrderedDicts remember the order items were added to the dict, rather than sorting them. You'd still need to sort each time you add an item to the dictionary (but that's probably still better than sorting on each draw).

Also looks like one of my new tests is playing up...

Oh indeed, TIL, OrderedDicts are mostly redundant.

Yeah this seems like the way to go, just running sorted on the dict when it an item is added.

LGTM, thanks! Auto merge enabled :)
