the extension produces warnings

[turl]

Hi, I was getting the following two warnings on my log file on GNOME 3.8

JS ERROR: !!!   WARNING: file '/home/user/.local/share/gnome-shell/extensions/temperature@xtranophilist/utilities.js' line 151 exception 0
JS ERROR: !!!   WARNING: 'assignment to undeclared variable line'
JS ERROR: !!!   WARNING: file '/home/user/.local/share/gnome-shell/extensions/temperature@xtranophilist/utilities.js' line 53 exception 0 
JS ERROR: !!!   WARNING: 'assignment to undeclared variable r'

I did the following changes to the code and it seems to be working ok and without the warnings
