   Use our own escape character parser.

   We're currently using the spirit escaped character parser. This is a
   strict C parser and causes parse errors for code that we probably should
   accept, such as any hexadecimal encoded characters with a value greater
   than the maximum value of the current platform's 'char'.  This is \x7F
   on some platforms so it rejects '\x80' upwards. As well as rejecting
   characters that might be valid, it also means that quickbook will act
   differently on different platforms.

   In python strings, '\xaaa' is equivalent to '\xaa' + 'a', but the spirit
   parser interprets this as a character with value '0xaaa'. So we probably
   should accept these.

   I also think we should be liberal about what we accept. IMO it isn't our
   job to enforce correct C++/python, just to create a reasonable
   rendering of our input. So rather than write a parser which understands
   the various types of escapes, I just wrote one that ignores any
   character following a backslash.

   Refs #2860.
