login after successfully creating user
join first season after post-user-creation login.

This is a hack to get going. Eventually this functionality will be taken over by the Home screen displaying multiple seasons.

Side note: There are tons of repeated method calls to build requests. This should be extracted at some point.
Landing page (view after successful login/creation) is a table view.

This is because I plan to launch directly into the current TAR season.
Eventually this will be replaced by a grid of season icons, but since there is only one no need to spend time figuring out that layout now.
