World|Line: Line::Side has ownership Segments; basic API for management
In the future this mechanism will be replaced entirely, so for now this simple implementation will suffice.
Todo for later: Both BspLeaf and Line::Side now implement a similar mechanism for management of "subelement geometries". This mechanism should be generalized with a uniform (likely URI based) method of addressing geometries (libdeng2's Bank seems to be a good fit).
