non-breaking strings. Attempt to break near whitespace.

- Find a better name than `pretty`.
- Add options for colored output, and allow custom formatting.
- Add option for colored output. Primarily syntax highlighting, but also
[BlueJ-style](www.bluej.org/about.html) scope highlighting, with some faint
background colors.
- Look more into `string.dump` in the core library.

Luckily Lua has a large library of pretty printers and serialization libraries:
If you want a sleek, fast, customizable or embeddable library, there are other
