Add "check for updates" option to tray icon.

1. What actually happened or you saw:
Right click on tray icon brings a menu with options.

2. What you wanted to happen or see:
I wanted to check for updates, but this option wasn’t there and had to open the main window.

3. Why you think it is desirable:
I think it will be much faster.

4. Any other information:

One could argue that your wish request might defy the purpose of the tray icon since there is an existent widget that aims at quick access.

As there has been no reply, I will move this report to “Added/Rejected Wishes” section.

Thank you.
