Andres G. Aragoneses 6cb03440c1 generator: generate all interfaces with the "I" prefix (.NET convention)
To be able to do this, Name property of GenBase class is now virtual, so
that it can be overriden in InterfaceGen with the new name.

Adapters, however, are still classes and then need special care as such
(cannot use the 'Name' property anymore), but this improves a bit the
readability of some parts of the code as the *Implementor and *Adapter
suffixes are now concentrated in just two new properties of GenBase and
not repeated all over the place.
