Update project01.md

Just made a few small changes:
* Added spacing and line breaks to the drawTree() description since some of the text was cut off on my browser
* Added instructions for importing the random module since that wasn't mentioned in the lab
* Added a t.seth(0) to the circle of triangles code, just in case a student's drawTriangle() doesn't automatically do that (mine initially did not and it made the output to regularPlay() look really strange)
