Plans for v0.4

[trystyncote]

This issue defines the plans for Scrivid version 0.4, which will primarily contain the AudioReference feature.

AudioReference (#13)

AudioReference is supposed to be a sister feature to ImageReference. It references the audio stream instead of the video stream, but both are meant to be in parallel. And sometimes you just want a well-timed sound effect to do with your visual change. AudioReference is required to play nicely with the rest of the video-making process. It's likely going to be "drawn" in a different stream, after the video stream is finished with its drawing phase.

This also comes with the side effect of changing Properties behaviour, requiring properties that only pertain to a specific type of reference, so Properties may need to be split based on functionality, or Properties needs a way to understand when there is a confliction of when the properties have image-only, and audio-only, properties present.

• AudioReference Implemented
• Update to Properties

This is doubtlessly a big feature just by itself.

...!

There will be more features defined in the future, but I have no ideas yet. :)
