New port: devel/py-prettyprinter

PrettyPrinter is a Syntax-highlighting, declarative and composable pretty
printer.

Key Features:

• Drop in replacement for the standard library pprint: just rename pprint to prettyprinter in your imports.
• Uses a modified Wadler-Leijen layout algorithm for optimal formatting.
• Write pretty printers for your own types with a dead simple, declarative interface.
