[Suggestion] Fix module compatibility with CSS override

[SMNFXCN]

Hi,
I am using MMM-OnSpotify with this module, and it has a feature to do a custom css override, changing the color of certain elements.
With the relative path options enabled, the path text is dark grey, I tried to get this module working with it until I discovered a fix. On Line 90 of the module's .js file, if you change
element.className = "dimm small regular"; to element.className = "dimmed small regular";, it lets the path text be compatible with MMM-OnSpotify's CSS override.
