Extract react-router-dom functionality from PR

[TimDaub]

Scope

• @dmihal has added react-router-dom support in this PR Add react router #194
• It's however entangled with other functionality currently, namely adding a TransactionStore and a config.js
• Given that we're now working according to a specification outlined by @dmihal here, which parts of the added functionality we want in master
• In my opinion: We can definitely use the react-router-dom integration. I'm unsure about config.js and the TransactionStore at this point. Please comment below if you have other ideas.

Deliverables

• Given the argumentation above, extract the react-router-dom functionality in Add react router #194 and propose it at separate PR.
