Changes

 * moved inline CSS to stylesheet:
 * – simplifies formatting changes (normal CSS simpler than inline CSS);
 * – eliminates server load when changing the formatting (no transclusion costs with stylesheets).
 * integrated navigation arrows and section parentheses using ParserFunction logic:
 * – easier to use the template;
 * – much easier to change symbols or formatting (no longer dependant on status quo).
 * added ParserFunction check for unspecified author:
 * – eliminates need to use parameter overrides for works with no authors.
