// OpenIssue registers a handler that will cause the bot to open a github issue
// based on the event text.
//
// The handler is registered as a "Respond", not a "Listen" (see the docs for
// github.com/ajm188/slack for the difference). The pattern which will cause
// the handler to fire has the form 'issue me // <owner>/<repo> "<title>"
// ("<body>" ("<assignee>")?)?'.
//
// The function takes as arguments the bot to which it should register the
// handler, and a reference to a client that can authenticate with Github. If
// no client is provided, then OpenIssue will fall back to using the
// package-wide SharedClient.
//
// Users should note that an attempt to assign an issue to a Github user that
// is not a "contributor" on the repository will result in a 422 returned by
// the Github API. This will prevent the issue from being created.
//
// When an issue has successfully been created, the bot will reply to the user
// which triggered the handler with a link to the issue.
