Add react router to persist internal state

[paolareategui]

Progress made:

• Using routes to navigate through the main tabs. A page refresh returns to the same tab.
• Creating dynamic routes to navigate through existing forms. The URL changes accordingly when a form tab is clicked.

Issues (work in progress):

• Unexpected behaviour happens when moving the forms. The tab moves but the page doesn't change. And the tabIndex will go past 0 (-1, -2 ...).
• After deleting a form, the URL remains unchanged (it should navigate to the next remaining form).
• Essentially, the tabs "need" to be activated (clicked) every time to work correctly.

Completed:

1. Static routes are implemented for the main tabs.
2. Dynamics routes are created to navigate through the forms.
3. After a refresh the user will stay on the same tab and route.
4. Creating, moving and deleting forms will navigate to the correct view and route.

Issue:

I get this warning when I navigate to the "Export" tab for some reason. Even though I didn't touch this component.

"Selector unknown returned the root state when called. This can lead to unnecessary rerenders.
Selectors that return the entire state are almost certainly a mistake, as they will cause a rerender whenever anything in state changes."
