Double comma between basic functions on model classes

[kgomes@mbari.org]

In Secha designer, if I add more than one 'Basic Function' to a model class, designer puts two commas between each function which then breaks the JavaScript. I can't find any way to get around this as even if I edit the code outside of designer, when I restart it, it puts it back in.

We're doing a lot of work in regard to codegen changes right now. I'll verify that this will work in the next release.
