basic sublime text highlighter syntax (for bat)

This is mostly based on the syntax generated by `isabelle
vscode_grammar` for the list of keywords; choice of scopes is heavily
biased by my understanding of the subset of isabelle syntax I actually
know about.

For now, it makes no attempt to actually understand anything of what is
going on in a file (except for strings/comments) and simply matches
keywords.

Note that scope selection does not make sense, and is mostly based on
looking into which scopes are assigned useful colours by common
highlighter themes (mostly bat's default theme and TwoDark for now)
