Subject: Moved all the text method stuff into text.moon instead of splitting
 across string2/containers. Modified the type stuff to output better type
 names and use (a Dict) and (a List) instead of (Dict) and (List). (Text) now
 also has a proper constructor. (assume) now also handles a bunch of different
 assumptions with smart error messages.
