mmm-util:
* changed release plan: version 3.0.1 -> 3.1.0 due to number of changes
* remove copy attributes stuff (at least for the next release)
* Added TransferObject and related stuff
* Added PersistenceEntity (and moved STATE_* properties there, incompatible change but will never hurt anybody)
#19: Create UiWidget layer
* improved list widget API
* improved value handling (propagate forUser flag)
