reg_dottedname incorrectly using InterfaceClass

In views.py line 182, I am not entirely sure why you are using ``reg_klass.__class__.__name__`` but it appears to be giving the wrong value here. It might be easier to explain with an example:

reg_klass:
dottedname = wicked.fieldevent.interfaces.InterfaceClass

It should be "wicked.fieldevent.interfaces.IFieldValueSetter". inspect.isclass expects a type in (, ) which type(reg_klass) does not satisfy. Maybe it should check if isinstance(reg_klass, InterfaceClass)?

`(Pdb) reg_klass

(Pdb) type(reg_klass)
`

If I correct the URL to fix the reg_dottedname I get the expected behavior.

Start at views.py line 182 and inspect how reg_klass is converted into reg_dottedname, using the reported InterfaceClass example as the failing case. Confirm that the generated URL uses the expected "wicked.fieldevent.interfaces.IFieldValueSetter" dotted name and verify the corrected URL produces the expected behavior.
