Fixed LED not showing color of last LED

[atekautz]

Use the option "fixed: 1"
leds: 16
The first LED (fixed one) changes color similar to the color of the last lit LED in the strip - but:
if the last lit LED is the first one with a new color the fixed LED shows the color of (last LED)-1
So if you have 3 green LEDs and one yellow in the strip, the fixed LED will show green. If there are 3 green and 2 yellow LEDs in the strip, the fixed LED will show yellow as wanted
