Added method for adding a list of triggers to a job.

Added a simple method for adding a list of triggers to a job. Not sure if this was the best way of doing this but it solved my problem. Any comments/criticism are welcome.
That's for the PR. If I could make one tweak, the naming style we've been using in this project and others would make this method name "WithTriggers". If you'll make that change on these two methods I'll take this in.
