*** BREAKING CHANGE *** Issue 155: Mapper <> JSON

[Jeppe Nejsum Madsen]

The changes mentioned here has been committed to master:
http://groups.google.com/group/liftweb/browse_frm/thread/8db6bbb93c16e0f5/e9c3cdce2f011313?lnk=gst&q=MappedField.name%2C+affects+Mappe#e9c3cdce2f011313

This means that MappedField.name is no longer lower cased, but
preserves the case of the field. This in turn means the JSON
representation of the mapped field will change.
