/*
system-monitor@ebbes applet
Cinnamon applet displaying system informations in gnome shell status bar, such as memory usage, cpu usage, network rates…
forked from gnome-shell extension (for gnome-shell 3.2) to Cinnamon applet by [email protected]
Changes that were done:
* Removed battery functionality
* Removed tooltips (as they were crashing Cinnamon)
* Implemented simpler tooltips
* Some backports from gnome-shell 3.4 extension
* Some small changes I liked
