Added helper script for emailing to Jive social collaboration systems

This has been reviewed and tested internally at my work, so I can't provide any links to that data.

I think this should be added as there are many Jive instances out there and it can be very difficult to train everyone on the details of emailing the systems. This ensures at the least that the email content will get through to Jive and not interrupted by some special character that seems innocuous. And it has added functionality for simple formatting that can be applied for advanced presentation.
