Allow track coloring by date

If you deal a lot with multi day trips, Locus misses the opportunity to easily display different tracks in different colors. Import e.g. http://www.alpenzorro.de/download.php?trip=ozeanix (128 tracks ATM, my current tour) and it will all be one huge blue messy line.

I would love a new color mode for track folders: "Date". Locus would simply pick the first points timestamp, do a daynumber modulo 3 and pick one of three high contrast colors for the track (suggest full blue, full pink, full red, good on almost any map).

Result: all tracks will get nicely different colors in a heart beat. something that otherwise requires over a thousand or so maddening taps. Try it manually... it's horrible :)

Estimated implementation time including testing: 30 minutes :)
