VC6 seems to have a strange bug with escaped quotes used in strings passed to
macros and failed to compile the original code with nonsensical error messages.
Use single quotes to try to work around this issue. They are also somewhat
more readable as they don't need to be escaped inside C strings.

This code is not used anywhere yet, this commit only adds the parser for the
markup and the related classes as well as the corresponding unit test.
