wired-up XmlDropDownPicker to Relations
removed local build event from project
added SaveFormat config to XmlListPicker (currently supports CSV / XML)
added SafeFormat option to EnumListPicker and SqlListPicker
split code out from PickerResource into SaveFormatResource
added SaveFormat config to XmlDropDownPicker (RelationTypeMapping now queries SaveFormat)

all Pickers now support SaveFormat config
all Pickers now support RelationTypeMapping
SaveFormat defaults to CSV
aligned all api controllers to use the same plugin namespace (with a view to moving api controllers out of the property editors folder)
POC for Relation Matches (wired up as a picker, so needs refactoring)
added contextId parameter to all picker getEditorOption calls (non-breaking)
RelationMatches functional
