Re: Change in the unittype and linktype interface

Here comes another change: the UnitFactory::init and LinkFactory::init 
functions now
take one additional argument,  their own name.
To be precise, they expect the name and major version separated by a ":".
(Example: "RandomUnitFactory:1")

Reason for the change: to give the freeframe plugin the possibility to 
detect which freeframe shared library
is associated with a UnitFactory.
