Bass strip polishing

 - Default to 144-long bass strips again
 - Strip hue waver is now configurable
 - The position on the bass strip that effects start at (edges or center) is now also configurable
 - Bass strip hue shift config tweaked, now allows for more granularity (hue shift went from short to float)
