Allow columns to filter issues

[devdrops]

As it seems, many organizations raise issues that are basic and, most of the time, easy to fix. Then they apply some specific label to identify such kind of issues (like https://github.com/issues?utf8=%E2%9C%93&q=is:open+is:issue+org:zendframework+label:EasyFix). Problem is, most of the contributors doesn't have the time to fix these issues. So that's exactly when other developers raise their hands and start to hunt these small but important tasks. That's the power of the community 😉

As a developer, I'd like to be notified whenever an issue labeled by a list of labels, by creating a new column filter. Nothing too much fancy: only a filter option where I can shove some labels in a list (I heard comma separated? 😜), and then use it to filter only results that match these labels. This could help a lot not only the devs that wish to contribute but also the projects itself.
