Adds HelpRequest Handler (#10)

* Adds basic handler for presenting slack user with dialog to request help for a service

* Swap out old example handler for help handler

This commit removes the DialogTest handler that was used for testing.
main.go now uses the HelpRequest handler when '/slack/command/help' is
hit.
