- removing filename attribute from rendering engine, wasn't working properly and redundant with name property

- misc ui fixes per usability meeting this morning
- using action node path in XFormsBean since current path isn't reliable in workflow context
- getting location column to work in manage task screen.  had to use actioncontext.id for wcm actions since path can be a Path object in workflow screens
- adding property resolvers to AVMNode for common props
