Nim implementations for The Computer Language Benchmarks Game

Compared to C implementations from http://benchmarksgame.alioth.debian.org/ . These are among the fastest. All benchmarks run on my Intel Core2Quad Q9300, x86_64, single core. I'm running Linux with gcc 4.9.2, clang 3.5.1 and nim from devel branch.

See each file for information about where it's from. Contributions are welcome.
