New method for producing man pages.

This change adds `--man1` and `--man5` options to pandoc, so
pandoc can generate its own man pages.

It removes the old overly complex method of building a separate
executable (but not installing it) just to create the man pages.

The man pages are no longer automatically created in the build
process.

The man/ directory has been removed.  The man page templates
have been moved to data/.

New unexported module:  Text.Pandoc.ManPages.

Text.Pandoc.Data now exports readmeFile, and `readDataFile`
knows how to find README.

Closes #2190.
