Option to exclude in-lining CSS declarations

[nagarjun]

Would be great if there was a way to exclude the CSS from being inlined. In a lot of server environments, people use tools like this to programmatically in-line CSS into HTML email templates. We do this too so we can maintain a "core" set of declarations that control branding etc. and an template-specific style.css file.

This way, we wouldn't have to change the in-line styles of every email template whenever we make changes to our global styles + it gives us the chance to create truly dynamic transactional emails.

Otherwise, this is an AMAZING and essential plugin. You're saving me a lot of time! Thank you.
