Render dialog can prepopulate better

## Use Case

Which fields should re-populate or be remembered when the render dialog is opened?

Start time and end time? (currently the logic is that the time you were on in interactive mode is deposited in the Render dialog as the Start Time.

Should the default output directory or file name include the loaded image name? And/or should it remember previous?

Should the image name be presented closer to the top of the dialog in addition to (or instead of) at the progress bar?
