Done with making the 1.3 docs point to the relevant 2.2 docs.

To Do List

=======================

- The 1.3 docs need to have links from each directive forward to the

  /docs/current/ version of that directive, or a note that it's not

  available in this century. See core.html for examples of how this

  might be done. This is a large undertaking, and involves a lot of

  grunt work, but will be greatly appreciated by the folks that make it

  to the wrong doc via Google. (Update: This is clearly going to take

  many months of effort, due to the volume of work and the mind-numbing

  tediousness.)

- Update the http://httpd.apache.org/docs-project/docsformat.html

  document to be useful. In particular:

    - Document the various macros that can be used in documents.
