How about getting GitHub username with GitHub API ?

Nobody has claimed this yet.

Like [yeoman/generator-generator/app/index.js](https://github.com/yeoman/generator-generator/blob/master/app/index.js).

``` js
var GitHubApi = require('github');

github.user.getFrom({
user: name
}, function (err, res) {
if (err) {
log.error('Cannot fetch your github profile. Make sure you\'ve typed it correctly.');
res = emptyGithubRes;
}

cb(JSON.parse(JSON.stringify(res)));
})
```

Start by reading the referenced yeoman/generator-generator/app/index.js example and compare it with generator-taskr's existing generator entry points. The work is done when the generator can obtain the GitHub username through the API and use the shown error fallback when the profile cannot be fetched.
