Route screen: Next/Nrevious Poute buttons missing, makes the app clumsy

version: latest ios

When looking at a sector, there is Next Sector and Previous Sector buttons. When looking at a route, there is no way to jump to next route and previous route. This make app usage slow and clumsy.

Fixes:

• Add next route and previous route buttons to route screen.

• Allow swiping left/right to next/previous route.

Route screen: no next/prev buttons, bad

sector screen: next/prev buttons under the image, good
