feat(ui): added js routing, updated ingame ui, added tricktable (#50)

This merge request has full JS routing for calling specific endpoints. Game is fully playable but doesn't have polling yet. This version already has the UI changes adressed in MR #43 so first merge MR #43 and then this one or only merge this one because it already has the UI changes :)
