Add Help Wanted issues to Code.gov

[jcastle-zz]

It looks like you have quite a few Help Wanted issues in your repo. You can feature these on Code.gov and reach a larger audience by adding specific tags to your Help Wanted issues.

Here are the specifics - https://github.com/GSA/code-gov/blob/master/HelpWanted.md And, an example - https://github.com/GSA/code-gov-web/issues/417

Let me know if you have questions, Cheers! Joe
