The Benchmark Suite currently contains two template benchmarks (Django and Spitfire) for Python 2.x, but none that support 3.x.

The attached patch adds a benchmark using Mako (http://www.makotemplates.org/), a popular, pure-Python, performance-oriented template system that supports both 2.x and 3.x via 2to3 conversion.

Mako is added to the "py3k" benchmark group and a new group called "template" with all three template benchmarks is added (that will only work on 2.x since it uses Django and Spitfire).

I added the Mako benchmark and lib to the lists in the README file and also updated the descriptions of the pickle benchmarks there since I had missed that before. Also fixed a path in there that was referring to perf.py as unladen-benchmarks/perf.py.
