Fix some #saveoptions issues

The #name default key was 'N', but that gets bound to #runsoutheast
when not using number_pad. Swap around the default #name key to M-n,
and bind the 'N' to it in commands_init instead.

The number_pad option wasn't getting saved because it has a separate
handler - mark the option as changed even if the value did not change
so it will be saved to the config.
