DownloadManager: Always use Nintendo servers + additional streamlining

- Download manager now always uses Nintendo servers. Requires only a valid OTP and SEEPROM dump so you can use it in combination with a Pretendo setup even without a NNID
- Account drop down removed from download manager since it's not required
- Internally all our API requests now support overriding which service to use
- Drop support for act-url and ecs-url command line parameters. Usage of network_services.xml ("custom" option in the UI) is preferred
