Run New Collection Account wizard in its own window
From Edit -> Accounts, when selecting Add -> Collection Account, pressing Esc doesn't return to the main Accounts window.
This is possibly because, in contrast to every other account type, it resuses the Accounts window, instead of spawning a new "create" window.
This also makes it easy to inadvertently close the Accounts window when trying to just cancel the account creation by clicking the close button.
Finally, having only back/next buttons means cancelling the creation at a late stage is a multi-click process (back-back-back).
I'd suggest that "new collection account" should be moved to a separate window to fix all of these issues.
