Adds seda timeout

Aaron - what do you think of adding this? We specify CamelVersion 2.21 in our build setup, so the timeout of 0 (default) should disable the timeout, if a user doesn't want one. (http://camel.apache.org/seda.html)

James Creel was asking for this type of change, as he's seeing issues: We're having an issue here where it times out processing a very large collection. He thinks this will fix it.

That being said, he's using Aaron Birklands fork of Elliot Metzgers repo - which is a somewhat outdated copy of ours: https://github.com/birkland/repository-extension-services

I've asked Aaron if he'll be updating that anytime soon.
