Highlight

This release removes the list of pending updates from the systray's tooltip. Indeed, having the list of pending updates in the tooltip was a bad design from the start and it creates more issues than it solves. The right click / dropdown menu is arguably a way better design for the same purpose (both in terms of UI and UX).
See #319 for full rational.

Additionally, this release brings some minor improvements to the libraries and systray scripts to ease their maintenance.
