nicer error message on rql constraints

implements 'parent' method on workflow entity types

this invalid constraint now fails with new constraints checking

this constraint is actually unusable in yams schema for cw

unused since a long time now

finish yesterday work on rql constraints: * Fix inheritance pb: there are some places where we filter constraints according to the class hierarchy, so rql unique constraint should'nt be neither a RQLContraint nor a RQLVocabularyConstraint subclass. Added test in unittest_schema reflecting this. * So now we have to get explicitly RQLUniqueConstraint where desired (eg in server/hooks.py) * Update i18ncubicweb command to include constraint types in generated pot file (this should have been there for a while...) * Update unittest_schemaserial which has been broken when serializing format for rql constraints has changed

synchronize rdef where unique constraints have been updated/added

oops, should have been updated

add a fourth item to 'view box' defintion, dispctrl, so that we can later globally sort all boxes instead of having view boxes before component boxes. 'view' boxes order is configured through uicfg.primaryview_display_ctrl, 'component' boxes order through the cwproperty system.
