Add ability to run dev ruby server with SSL

+Sometimes there is a need to test the app with an SSL connection, for example for
+testing pusher on Travis CI Pro.
+
+In order to run the app with SSL enabled you need to:
+
+* generate self signed certificate as described here: https://gist.github.com/trcarden/3295935
+  * one difference is that you need to use localhost.ssl, because travis-api
+    doesn't whitelist localhost.ssl at the moment
+* run ruby server with `SSL=true TRAVIS_PRO=true waiter/script/server`
+* run Ember app in build mode only `TRAVIS_PRO=true ember build --watch`
+
+Now open the app on whatever port ruby server is running (3001 by default). The
+ruby app will serve files generated by `ember build` and it will allow SSL
+connections
