What's funny is that I didn't copy from the wiki page. I copied from a hash function from within the file. I suppose that means the other hash function is using spaces as well? I'll fix them both on commit.

As a result, when data was pulled from the database, the config framework barfed, saying it didn't know what these object fields were. For config files, this practice is fantastic. It makes sure to raise a giant red flag to people that they are attempting to configure something that is not recognized by Asterisk. For realtime, on the other hand, it is legitimate for a database to contain supplemental data alongside the data Asterisk cares about.

In addition, I have created two realtime sorcery unit tests. The first one simply creates data in a realtime backend and then has sorcery atttempt to retrieve the data, ensuring that an object is allocated with the expected data. The second test is similar, except that in addition to the data that has been registered with sorcery, an additional field is created in the realtime backend. This test ensures that the data can still be retrieved and successfully allocated by sorcery.

I initally wanted to make this a NOTICE-level message, but I was afraid that with the frequency with which objects are retrieved from realtime, this could spam the logs a little too much. On the other hand, leaving it as a level 1 debug message I have now could make it difficult for someone that has misconfigured their database (say they accidentally have a typo in a column name) from seeing that data they expect to be relevant is being ignored by Asterisk. Any suggestions on how to handle this?
