In December, they removed the NEW Apps tab in the Discovery section, as well as the ability to access arbitrary URLs. (as you indicated). For testing, I usually use the Chrome extension or access my test server via the chat URL.
But since the NEW tab has now been removed, it is now impossible to release new Kik applications, since people will only be able to recognize your application using the search function, and getting into the top 100 will be very inconvenient here. I contacted Kik if removing the NEW tab was a permanent change, to which I received a response that they are currently rebuilding their platform and new solutions towards what they are moving.
So, if u is currently working on the Kik App, I would recommend waiting with its release until possible future Kik browser updates are released.
As for your other question, to get the crawler to find your application, you just need to add some meta tags to your header:
<meta name="description" content="app description"> <link rel="kik-icon" href="your image")"> <link rel="canonical" href="your domain"> <script src="http://cdn.kik.com/kik/2.0.5/kik.js"></script>
