Working on Manjaro 18.1.5, Xfce stable, 4.19.96-1 kernel, with Python 3.8

[Armag67]

Hello,

Due to a switching from amperes to watts for power supply in the latest kernels updates, I had to slightly modify cpug.py and investigator.py to make this application work properly on my Manjaro (18.1.5, Xfce stable, kernel 4.19.96-1, Pyhon 3.8.1) box with french locale and displaying now Xorg version, accurate distro logo, battery charges: now, full, full design and power now with the good units (Wh & W).

There is also a subtle bug in the sysdevcpu function in investigator.py. This bug only occur if /proc/cpuinfo and /sys/devices/system/cpu/ don't return the same number of cores. Then sysdevcpu function try to print:

            print("Error: Cannot decide if the cores are %s or %s.\n" +
                  "Using the lowest value as the real cores number." %
                  (self.cpuinfo('coresnum'), coresinsysdev))

which is buggy and should be replaced by:

            print("Error: Cannot decide if the cores are %s or %s.\n"
                  % (self.cpuinfo('coresnum'), coresinsysdev) +
                  "Using the lowest value as the real cores number.")

I suggest that the python-distro module must be added to the dependencies in order to use all my suggested modifications in the two diff files (in the attached tar.gz part) which covers the different modifications that I think are necessary.

Thanks to take a look.
