Render functions behaviour changed without notice

[miljan-aleksic]

Since version 2.0.2 there are subtle changes in how createElement behave.

1. The createElement first argument, if a String, can only by HTML tag. Prior it was accepting globally registered components.
2. The render function must return some value. Before it was not getting rendered without rising errors.

Both examples raise the Cannot set property 'functionalContext' of undefined error.

Correction on point 1. It still support custom components, which could be documented, btw.

Correction on point 2, its about Functional Components. They should be able to return anything, even empty string if required, right?
