Modified str parser to capture apostrophes in smart mode.

This solves a problem stemming from the fact that a parser
doesn't know what came *before* in the input stream.

Previously pandoc would parse

D'oh l'*aide*

as containing a single quoted "oh l", when both `'`s should
be apostrophes.  (Issue #360.)  There are two issues here.

(a) It is obvious that the first `'` is not an open quote,
becaues of the preceding `D`. This patch solves the problem.

(b) It is obvious to us that the second `'` is not an
open quote, because we see that *aide* is some text.
But getting a good algorithm that has good performance is
a bit tricky.  You can't assume that `'` followed by `*`
is always an apostrophe:

*'this is quoted'*

This patch does not fix (b).
