Pass options through on include

Pass template parse options down through include tags. This will make them use the correct parser, as well as respect profiling and (eventually) line number options.

This PR can supersede #420 since it solves the same problem (I also included the test from there). It solves it in a way that is more general and also is easier to integrate with #419.

I don't think the option name is very clear without having the context of this pull request.  It isn't clear that this is referring to not passing down options to included templates.
