Title: Fix typos on turtles documentation.

* Add missing white space between words.
* Rename Serpinski => Sierpinski (the [mathematician](http://en.wikipedia.org/wiki/Wac%C5%82aw_Sierpi%C5%84ski)) only in the documentation.

Changes to executable example code will be in a separate commit / pull request (in case anyone depends on the misspelled name).
