Promote the server version from a local variable to a class variable,

so that a subclass can override it.

This partly addresses Bug #112634 -- but the documentation is still
wrong, since it suggests that you can set self.version *after* calling
the base class __init__.  In fact it must be done *before*.

I'll fix that too.
