Ability to move a sheet to a new parent folder (by ID)

[jethrowest]

Hi Mark,

Please could you add the functionality to change a Spreadsheet's parent folder ID?

Thanks,
Jethro

I tried something similar to the following based on Google API docs:

spreadsheet_instance.drive_service.files().update(fileId=file_id,
addParents=old_testplan_folder_id,
removeParents=spreadsheet_folder_id,
fields='id, parents').execute()

but this didn't work, complaining on the string type of the file_id :(
