Subject: [PATCH] Enable using an external mailer under windows.

1. this depends on the patch to fix tsrm I sent to dev
2. this provides backwards compatibility, as long as sendmail_path in the ini file is empty, the old internal mailer will be used, once sendmail_path is defined, the external sendmail program will be used.

I tested with indigomail from www.indigostar.com, which provides the same command line interface as sendmail no linux.
