Run mbox-to-Maildir conversion before loading modules.
Invoke the mbox-to-Maildir conversion directly from main(), just before the call to e_shell_load_modules(). The reason the code is here and not in the mail module is because we inform the user at startup of the impending mail conversion by displaying a popup dialog and waiting for confirmation. This has to be done before we load modules because some of the EShellBackends immediately add GMainContext sources that would otherwise get dispatched during gtk_dialog_run(), and we don't want then dispatched until after the conversion is complete.
