Closes #3019 - Implement default navigation

Default navigation for commands that jump to new locations has been
implemented with the `ale_default_navigation` variable, and all commands
that jump to locations now support `-tab`, `-split`, or `-vsplit`
arguments for overriding the default navigation behavior.
