[Koha] Statement of responsibility display w/ movies

[Cab Vinton]

This falls under the minor annoyance category, but user experience is
important so ...

Statements of responsibility for movies tend to be huge affairs -- a
tedious list of studios, producers, writers, directors, etc. -- like
so:

I'm fairly confident 99%+ of our patrons don't care about this
information & would prefer to not see it cluttering up the initial
results screen.

So I'm wondering if there's an elegant way of suppressing the
information in the 245 c subfield but only for particular item types
(i.e., movies). Or perhaps a way to display just the last clause
(usually the movie's director), following the final semi-colon.

Thoughts?
