Improvements to the @HtmlDoc annotation.

FYI....I've made the following modifications to the following @HtmlDoc annotations:

• links() - Now an array of strings instead of a JSON object. Simplified syntax. 
  For example:
  
  Previous syntax will still work, but you're encouraged to use the simplified syntax.
• Several annotations are now arrays of strings instead of simple strings. Values are simply concatenated with newlines which makes multi-line values cleaner.
  • header()
  • nav()
  • aside()
  • footer()
  • script()
  • style()
