Calling Subject() from application yields exception

[Narigo]

Hi Luka, I've updated my code to 0.13.6 from 0.9.1 and now it breaks whenever I try to create a Subject by doing Subject(), with the following error:

Subject.scala:47 Uncaught TypeError: Cannot read property 'Subject' of undefined
    at $c_Lrxscalajs_Subject$.apply__Lrxscalajs_Subject (Subject.scala:47)

I've made changes to my project so it's only calling Subject[Int]() after the main export here (branch subject-apply-reproducer), so you can disregard all other code... https://github.com/Narigo/scalajs-fun/blob/subject-apply-reproducer/scycle-examples/src/main/scala/com/campudus/scycle/examples/ScycleApp.scala#L20

I'm unsure what is different than before, but when doing the fastOptJS in sbt, it does not seem to work anymore. Did some dependency change or do I need to update something else in my build.sbt?

I think I found the problem. The "org.webjars.npm" % "rxjs" % "5.2.0" needs to be added not only to "test"! I really need to take a course in sbt.

Glad to see you figured this out! :)
