We happen to have support for converting such comma-separated values into a class array already (through a dedicated ClassArrayEditor), but not into a list of classes yet (where we're simply trying to convert such a case into a single entry via ClassEditor). I'll revise this for 4.3.1.

We're treating Class collections analogous to Enum collections now, pre-processing single values through comma separation.
