Add a read-only property for the current scene

[ianadeem]

A getter for the current scene has been added to the screen object. This is required for handling screen resizes when the main loop is run manually by clients using draw_next_frame.

Tests are still passing.

Closes #144.

I couldn't find a .stickler.yml file in this repository. I can make one for you, or you can create one by following the documentation.

Thanks!

My pleasure!
Do you have an ETA for when there might be a release with the fix?

[peterbrittain]

I was hoping to resolve #95 before creating a new release... Looks like the underlying issue is just sitting there, so maybe I'll submit my PR anyway and see whether that gets accepted.
