Improve builtin-func and highlight type annotations in func args
 * Builtin-functions are highlighted only when used as global functions. * Annotations in type-only variable definitions and assignment statements are not supported yet due to potential conflicts with dictionary expressions. * Uses a custom syntax highlight def "Optional" (in my setup, it applies italic style.) * Taken from purpleP/python-syntax commits and customized.
