better /weather command and a newly commented code!

So initally, my /gda-weather command only worked for Charlottesville (where I live), and only also in Fahrenheit (strictly inferior but sadly the only one I coherently understand). I started off today by doing some research into how to actually accomplish my goal of any city, any system. I actually ended up switching into a much better weather API that allowed me to tell the temperature by city. I am not particularly good at Javascript (for now), so I decided that the easiest way to have the difference in between Fahrenheit and Celsius was just to make a specifically Celsius version of the same /gda-weather command, /gda-celsius-weather. I know, so origional.
