Fix # 8414: Use the noweb module instead of literate-* article layouts

Now that we have module support for literate programming, it is possible to do a noweb cleanup. This is basically a patch from Kayvan Sylvan:

- get rid of literate-xxx classes
- rename Scrap to Chunk, since this is the name noweb doc uses (Scrap is from nuweb)
- update lyx file format and add lyx2lyx support for gettting rid of literate-xxx classes
- update documentation

On the top of it, update tex2lyx to
- avoid creating files with literate-xxx class
- fix conflict between parsing << as a quote and parsing it as a Chunk
- create Chunk layouts instead of Scrap ones.
