Add an internal Document representation

Doing everything on strings is kinda wonky, so this adds an intermediate
representation. The idea behind this is that the pipeline now goes

    Wikicode [1]-> Document [2]-> Output String

Where step 1 takes care of templates and everything, and step 2 does the
actual output formatting. This has the benefit that we can support
multiple output types, some with more and some with less features (e.g.,
adding a Markdown output which keeps some of the original formatting
intact), and it has the benefit of being less wonky (no hacks with
"<!NUM!>" for numbered lists, more streamlined formatting with newlines,
...).
