Custom blocks (Part 1)

ok, it's added to the color blocks library I made:
https://snap.berkeley.edu/snap/snap.html#present:Username=helicoptur&ProjectName=Color%20Blocks&editMode&noRun
it's not exact titles, but rather descriptions that probably include multiple words and non-alphanumeric symbols. i found the way of getting the exact title was too unreliable, but the way to get the description does work every time.
