Attach

Included the functionality of adding " Inline message" in the body of the mail from the _job file. Have also included a direct method which will do the attachment to the mail very conveniently for us. The methods have been added in the DefaultMailer.java. Both properties are configurable and can be added in the .properties file as "mail.attach.name" and "mail.inline.error" . As an input to the formal we can specify a regex like " *.logs " or " .*.job.* " etc. Hope this helps!
