Preserve the URL for import module from previous load and resolve duplicates

[dlealv]

Currently, if you want to import again a workbook from gist, you need to enter the URL every time, even if you want to do an import to a workbook whose content was imported already. To avoid duplication name, you need to remove the content of the workbook. It should not be necessary, AFE should resolve duplicates by replacing the old content with the new content for existing functions. Then add again the URL and import it. I understand if you click on +New, that the URL won't be preserved, but for an existing workbook that was loaded before using a given URL keep that information, so the user doesn't need to enter the same URL again.

Thanks in advance,

This would be an amazing improvement to AFE.
