New react planner release

[ghost]

I have seen that @JaccoGoris has added some useful features like Collada Exporter etc.

@danilosalvati will the new features be available in a new release? And when is a new release planned in general? Also are there any plans to implement the wall design improvements any time soon? https://github.com/cvdlab/react-planner/issues/88

Thank you very much!
