Add WEB translation

[chadwhitacre]

The World English Bible (WEB) is the most well-regarded modern translation of the Bible in the public domain. It was the foundation for the Eastern Orthodox Bible. I think it would make an excellent addition to Orthocal.info as a more modern alternative to KJV. A USFX file is available (in fact, I believe that the editor of the WEB invented USFX).

@brianglass and I discussed this in private email and I believe he is open to it. I am opening an issue here to track work on this publicly.

I did a little poking at this. I think there will need to be some refactoring as the system currently seems to assume one translation per natural language.

@chadwhitacre, I agree. Do you have any thoughts on how best to model this?
