Merge branch 'sticking-with-jekyll' of github.com:gvwilson/bc into sticking-with-jekyll
Modified build to generate Markdown files for IPython Notebooks in the source directories so that the Jekyll build will put all the files in the right places.  (Having a separate CACHED directory is cleaner, but then we have to move or patch files after the fact to make links resolve.)

them to ask how to modify an existing record. This demonstrates how to do
this using Update in a few lines.
Instructions for creating the sample database used in SQL lessons.

This replaces #702, which had a lot of other things folded into it - undoubtedly could have cherry-picked the necessary changes, but merging one file seems simpler.  All credit for this work goes to @rkiko and @svaksha.
