Title: do not add through associations if transitive option is turned off

Hi,

Thanks for improving railroad and making it great.

docs:
-t, --transitive Include transitive associations
(through inheritance)

I read: don't show :through associations unless -t flag is present.
Unfortunately, through associations are always displayed

Here is a patch to implement it.

If you have a different approach, please let me know and I'll fix.

Thanks,
Keenan
