Add Jobs Page with examples

OK, proceed with caution...this is my first attempt to fork, modify and submit a pull request.

The changes add a "Jobs" page to the site, along with several templates and sample pages. 

The Jobs page displays posts with categories "jobs" (intended to be job openings) and "talent" (resume's or job availability posts from members looking for jobs). Members would either create their own "jobs" or "talent" posts by submitting to the site, or I've offered up templates (md files) which can be completed and then emailed to me and I'll try to post them. 

See what you think. Not sure this is ready for prime time yet, but it seems like a good way to get it to you so you can check it out.
