Well, I think it's manage_changeProperties (nasty name for starters) that
deletes any property you don't include in its arguments, see the interfaces
wiki for details.

How about just replacing it with:

def modifyProperties(**kw)

...where kw is a dictionary mapping property name to property value. If it
property specified in kw didn't exist, it would be created.

Also, on addProperty and modifyProperties, how about making type coersion
happen and raise an exception if it fails?

so, if you did addProperty('test','string',1.234), addProperty would coerse
1.234 into the string '1.234' or raise an UncoercableException if it
couldn't?

Might be nice if the available property types were also documented
somewhere.
Hmm, also, coersion should check that when something is stored as the
'lines' property type, it only accepts a list of strings.

cheers,
