Support Activate and SecondaryActivate about gtk-sni-tray

[colonelpanic8]

Yes, the Host implementation is, as you have noticed, not technically complete, although the reality is that very few things properly implement the activate or secondaryACtivate methods here

This is generally one of the downsides of SNI as compared to XEMBED. There is a bit less flexibility WRT input.

@ARR8 @kurnevsky @nomeata You all expressed interest in this feature -- Do you have examples of sni apps that provide this functionality? @kurnevsky has implemented this in the latest version, but I haven't found any examples that I can use for testing.

@IvanMalison
For activate: qbittorrent, qtox, telegram-desktop, deadbeef use it for window showing/hiding.
For secondary activate:
deadbeef with https://github.com/vovochka404/deadbeef-statusnotifier-plugin uses it for play/pause toggle. Derivation: NixOS/nixpkgs#130534
pidgin with https://github.com/philipl/pidgin-indicator uses it to show/hide its roster. Derivation: https://github.com/kurnevsky/nixfiles/blob/master/modules/pidgin-indicator.nix

@kurnevsky I'm going to do a release of gtk-sni-tray soon (probably today). I've merged taffybar/status-notifier-item#8 . Were there some associated changes you wanted to make here that needed that PR?

Yes. I haven't tested it yet, but should be enough (itemIsMenu is available there and it defines the behavior of left button).

[colonelpanic8]

Does it? I don't see the code that does that.

[kurnevsky]

I mean specs say it defines :)
We should implement it in gtk-sni-tray with the help of itemIsMenu.
