Remove TBB reference; use curly quotes; update PDF.

Since we removed the text referencing TBB, I removed the corresponding
references entry.

I engaged the 'csquotes' package to turn our straight quotes to curly quotes.
This had the effect of turning double quotes into single quotes... probably
okay.

Oliver's tex -> PDF toolchain didn't render my double-dash properly; the
previous PDF had a long blank in that spot. My toolchain seems to treat that
case better?
