Allow flexibility in assignment of properties to table columns in VCS

In the default-repository-config.xml it's now possible to specify where each field goes, using <field> elements inside the <schema> element. <field table="tablename" column="columname">prefixed:fieldname</field> The table or column can be omitted if they don't need to be changed. If specified, they must be in the same case as in the schema defining the existing table (usually lowercase). The field must be prefixed if and only if the schema is defined with a prefix. For instance Nuxeo has an implicit configuration equivalent to the following (which you must not repeat): <schema> <field table="hierarchy" column="majorversion">major_version</field> <field table="hierarchy" column="minorversion">minor_version</field> </schema> If you want to move the dublincore title to the "hierarchy" table, you can do: <schema> <field table="hierarchy">dc:title</field> </schema>
