Get rid of the misleading JavaScript comment about placement.

It's kinda at the end of the page but not really, and it's unnecessary.
A few whitespace things on TypingText, nothing special.
Make hand-written JavaScript code a bit prettier.

The preceeding spaces are a bit odd and I'm working on them, but it's
not the end of the world to have those there since they signify that the
code is within the script tag.
