Lab HL7 Interface

I have been working on an interface with Quest Diagnostics to be able to automagically import HL7 v2.3 messages into FreeMED. They were nice enough to furnish me with some documentation, and I have an alpha-quality implementation ready for some beating in one of our alpha sites. Now that 0.8.0 is out, I’m working steadily on a 0.8.1 release, with mostly bugfixes, some rearchitecturing, and a few nice features like this one (hopefully).
