Doc improvements (#1729)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Split out AST 'printing'.

* Replace listener with List<Section>

* Section -> Part.

* Kind -> Type Flags -> Kind for ASTPrinter::Part

* Improve comments around ASTPrinter.

* toString -> toText on Val derived types. toText appends to a StringBuilder.

* Added toSlice free function.
Added operator<< for Val derived types.
Use << where appropriate in doing toText.

* More work at mark down output.

* Fill in sourceloc for enum case.
Add more sophisticated location determination for EnumCase.
Refactored documentation output into DocMarkdownWriter.

* Improvements for sig output.
