Fix many py2-style prints in docs and commented code....

Fix many py2-style prints in docs and commented code. The main interest was to transform py2-style print statements that still appeared in some docstrings (e.g. for %history) and would thus show up when looking at the docs either interactively or in the rendered website. I also fixed a number of commented-out print statements at the same time, mostly because it was easier for me to just regexp-change all of them so that I could focus on the others.
