seems like notification does not work anymore on windows after this pr

[HappyTobi]

I will Check that in the evening today and fix the issue.
I will also create some status icons for windows and linux

[jwallet]

im thinking about adding next to the status dot that you added ,a way to show that there is new activity without breaking the appearance of rocket.chat logo, something like how Slack does it for the tray icon, a blue dot (alert) and a red one (mentions) and when you hover the "Rocket.Chat+" title will change for "24 unread messages".

i will probably change those pics anyway but keeping the feature you added, the icon will just be the default tray_icon with the status dot next to it. but having all named files you created for osx would be nice.. there is no sign of these in the repo

[HappyTobi]

so i fixed the problem with the default tray_icon. Fix

There some differences between the platforms while showing the tray icons and status.

OS X:

• use the template icon's and an title tag to give you some information (the title will be uses to visualize the user state)
• there no special icons to show badge state because of the dock implementation.
• There is only one icon to show badge state (rocket with exclamation mark)

Windows / Linux:

• uses special icons for each badge state (1-9+)
• to show the user state we have to create some special icons (open)
