Dynamic fields for sale order line properties

This module allows to dynamically draw properties groups on sale order lines. That is, if you have a property group 'Length' and set it as 'Draw dynamically', the module will automatically add the x_length field to the sale order line and visualize it as char field in the form view. When fill the 'Length' field, the module will update the properties field (property_ids) according to it. This allows to set the line's properties through normal fields, instead of creating new properties or selecting existing properties.
