imap-send.c: remove namespace fields from struct imap
They are unused, and their removal means that a bunch of list-related infrastructure can be disposed of. It might be that the "NAMESPACE" response that is now skipped over in get_cmd_result() should never be sent by the server. But somebody would have to check the IMAP protocol and how we interact with the server to be sure. So for now I am leaving that branch of the "if" statement there.
