get rid of all bifold text

It's just uneconomic to maintain given how little I've used it. I have a
bug right now and no time to port the bugfix to all the complexities of
the B side.

I briefly considered tossing out the entire source editor. But I _have_
been using it to browse logs across sessions. The live editor doesn't
quite cover all my use cases just yet.

We now have duplication in the source editor only for:
* syntax highlighting
* hyperlinking [[WikiWords]]
* ability to hide cursor (when showing file browser or Focus is in log browser)
