Replicating the removed prefix option?

[robframpton]

I have a project that still uses v3.4.0 of this plugin which still makes use of the prefix option. The project uses a global instance of IncrementalDOM that is slightly modified from it's original state. Because of this our project isn't currently compatible with the newer moduleSource option, and it doesn't make sense to try and refactor at this point.

My question is, is there any way to replicate the old behavior of prefix with the latest release of this plugin?
