[Feature] Option to Export script with breakdown highlights

[hyuri]

Issue

We don't seem to have a way of exporting a screenplay PDF with the script breakdown highlights.

Proposal

Add option "Breakdown Highlights" to the "Export Document" dialog, so that the screenplay can be exported the way we see it in the Screenplay Breakdown module, with highlighted text.

What is the case? Why do you need to export screenplay with highlights, since elements not will be added anywhere?

3 main cases:

1. I want to attach the script breakdown to a submission for a production grant, together with other documents, to support/prove the budget and schedule;
2. I've broken down the screenplay and want to hand this work over to a 1st A.D. This is more for low-budget productions, of course, but still;
3. Archiving. Saving final documents is important, so it's easy to go back and check the work when necessary. Imagine in the future Starc's breakdown module has been completely revamped and the current file is no longer compatible. That means I wouldn't be able to open the breakdown to check, and would have to hunt for the right old version of Starc. It's just a mess we can avoid by simply being able to export the breakdown to PDF.
