Multi-value Frame Picklists

A new frame type of Picklist has been added to Project Setup. This is so an item type can have more picklists than can be defined through categories. Currently a category may be assigned to a text frame as part of the frame definition (when the category value is used to specify a colour for the frame). This has now been extended so that for picklist frames, the category defines the list of values to be shown in the picklist.
