Feature Proposal: Voiceline integration

[Fireye04]

Goal

Introduce smoother mechanics to adding discreet voice-acted recordings (or, heck, any audio file) to individual lines of dialogue.

Methodology

Add some form of drag & drop to allow developers to quickly drag audio files to their corresponding line of dialogue, then pass each audio file through to runtime along with its corresponding line of dialogue, to be played by the balloon when that line is fetched and displayed.

Proof of concept

I have an initial (currently non-functional) quick & dirty implementation of the idea here. I designed what I have so far to be as far out of the way of normal use of the plugin as possible, but available if needed (via toggle). The reason it's nonfunctional is that I'm unsure of the approved way of saving the file path data to the all-text resource, and can't run the data all the way through without that.

In Conclusion

Let me know what you think! I'm happy to scrap as much of what I've done so far as necessary, just looking to hopefully streamline the VO process as much as possible.
