OU Harvard improvements

[pmelchor]

• Change documentation URL for easier access to the PDF version, which does not require an OU login
• Create 'director' macro for use in film references
• 'access' macro: use the 'available at' term instead of hardcoded text; replace hardcoded spacing with group delimiter
• Prepare citation and bibliography for type specific formats
• Create type specific formats for films

Example of film citation:
(Lord of the Rings: The Two Towers, 2003)

Example of film bibliography reference:
Lord of the Rings: The Two Towers (2003) Directed by Peter Jackson [Film]. New York, Newline Productions Inc.
