Delay file creation when a new file is created in the file manager.

[drgrice1]

Instead of creating the file when the new file confirmation page is submitted, create the file when "Save" (or "Save As") is clicked from the edit page that opens next.

This was requested in issue #2326.

Also, don't focus the name input on the edit page. That is a bit annoying. Only focus that input on the confirmation page. That is the only page that has a data input.

Works as described, thanks!
