Create a nice view for open "help wanted" issues

[arirawr]

Dependent on #24.

Describe the solution you'd like
We should have a page that shows a list of currently open issues tagged with "help wanted", which matches our design.
Should show title, repo, date opened, and tags.

I'm happy to help with the design aspect if needed.

While working on #24 I've come across the API query that will fetch all currently open issues with the "help wanted" label in Embark repos: https://api.github.com/search/issues?q=+org:EmbarkStudios+type:issue+is:open+label:%22help%20wanted%22&sort=created&order=asc. It just needs to be filtered to get issues from the repos in data.json.

Posting this in case anyone wants to get started with this issue, as I don't think it necessarily needs to depend on #24 if implemented this way.

Also, as an aside, "help wanted" can be replaced with "good first issues" to get all the good first issues. I think having a view that shows those might be helpful to people just getting started.

@guimcaballero oh that is a pretty neat query to gather it all, didn't know one can do it across an entire org, looks promising!

we have a tags page @arirawr , does this issue require a new /helpwanted page?
