feature request: show an icon in desktop notification

[mervn]

Tiny notifications currently do not display (or request) an icon. This is negligible but can be jarring in some environments where every notification has an icon.

Here is a patch:

@@ -33,7 +33,7 @@ impl Default for Notifier {
 #[cfg(feature = "desktop-notifications")]
 fn notify(summary: &str, body: &str) {
     // TODO: Report errors somehow
-    let _ = Notification::new().summary(summary).body(body).show();
+    let _ = Notification::new().summary(summary).body(body).icon("tiny").show();
 }
 
 #[cfg(not(feature = "desktop-notifications"))]

This patch works whether or not an icon is available, but I can only make this claim from my machine. It's likely notify-rust is robust enough to handle missing icons.

I've included this as an issue instead of a PR to see if there's interest in generalizing this (user chooses name of icon in config; maybe per server?) and to discuss if tiny could get an official icon.
