Subject: Allow preambles to omit the tikzit-specific preview stuff

The editable preambles include a bunch of things that *have* to be there
for previews to work, which makes figuring out what you can edit hard.

We now add a \documentclass automagically if it is missing, and if
\begin{document} is missing, we assume the preview-specific stuff should
be added.

OSX changes are untested.
