There are two ways to handle this.

1. Create a new global variable, with appropriate prefix, to hold
   project plist, e.g., `org-publish-project-plist';

2. Require preparation functions to accept one parameter, the project
   plist.

I'd favor the second one. In any case, the manual should be updated
accordingly.

WDYT?
