this commit fixes 2 problems:

-there was a trailing comma in the clock module that would interact badly with i3pystatus & i3bar; i3pystatus seeing the comma would generate the json ** full_text : ["13 september"] ** and then i3bar would only display the last module (one may have to check for i3bar robustness). resulted in having only the clock module displayed
-the 2nd problem was with the alsa module when setting the volume to a number <0 or > 100 then the pyalsa bindings would generate the following error in .xsession-errors
