better quote handling in markdown reader

[GoogleCodeExporter]

Currently the markdown reader's quoted parser ignores curly double and single 
quotes.  This is okay for some kinds of output, but not for others.  It would 
be best to produce a Quoted inline consistently, whether or not curly quotes 
are used.

Also, the parser should be able to handle the American standard of putting an 
open quote
at the beginning of a paragraph with no close quote, if the same speaker is 
speaking in the
next paragraph.

The first part resolved by 7864f30717767f89ee33532b59819b51ef2e14d4

The second part (open quote with no close quote) dropped on closer 
consideration.  It's a bad idea, because the writers will just put the close 
quote in.
