Chore/update dependencies

[maschino]

Summary

This PR turned out to be not as straight forward as I thought. I've updated all the dependencies, especially reactstrap to 7.1.0 - their breaking change introduced an render time crash if our plaintext mode was used. This is fixed with this release. Due to the reactstrap update I'll bump our version to 3.0.0.
