Notification about high temperature

[UshakovVasilii]

Could you consider adding a possibility of displaying a pop-up notification once the temperature at certain sensors reaches a specified value? Currently Linux boxes just forcibly shut down once the CPU is hot enough, which is a serious usability problem and may cause people to lose their work. Ideally, the extension should automatically detect the critical temperature for a sensor and set the default alarm temperature at, say, 5 degrees lower value. Also, there should be an option to hide any icons on the panel while temperature is normal.
