Title: Rework mandlebrot.jl for 3x speedup

This is a great benchmark to show off Julia's speed and conciseness. Not only is Julia only 1.5x the fastest C/C++ (2x Fortran, the fastest overall), it's leagues ahead of other dynamic languages. It also has one of the most concise and readable implementations, a great highlight to its careful language design.
