Bugfix Release
When running exercism fetch, files that were previously fetched would get overwritten. This is particularly annoying if you've edited the test suite, or if you were working off of a stub file.
Note: If you are using Mac OS X choose one of the darwin binaries. If you're unsure of whether it's a 32 bit (386) or 64 bit (amd64) then take a look at this page.
