Mini: Updating package.json > devDependencies > microtime to ~0.6.0

The command `npm install` on `nodejs=v0.11.13` and `npm=v1.4.9` fails with error

``` javascript
10117 error microtime@0.5.1 install: `node-gyp rebuild`
10117 error Exit status 1
10118 error Failed at the microtime@0.5.1 install script.
10118 error This is most likely a problem with the microtime package,
10118 error not with npm itself.

10118 error     node-gyp rebuild
10118 error You can get their info via:
10118 error     npm owner ls microtime

Changing microtime's version to `0.6.0` works. I see all tests are green.
