* Added setCustomTopBodyElement allowing to define custom HTML to be added at the top of the "<body>" tag.
* Change custom top body element to 'header'
This will make more sense once a footer is added. No functional changes.
* Make custom header concat conditional
Matching the _bodyClass comparison above
* Create getHTTPEnd function
* Add custom body footer functionality
* Fix <small> close tag on update page
* Add missing HTTP ends to exit and close
* Remove 'immediately' from header/footer desc
It's not immediate, the 'wrap' div is added before/after.

* Add body classes argument
Note that the additional function argument for getHTTPHead() includes a default argument for backwards compatibility with the API.
* Add page-specific classes
Allows easy styling of each page
* Change root CSS class to 'home'
Trying to avoid confusion between the class for the root level and the CSS ":root" pseudo-class
* Use conditional body class spacing
Avoids an extra space if a body class is set, but an empty string is passed to the function
