Some small fix
virt: Replace Versionable class with new version.

new version
pros) multiple version of class in one process
      change version of class by parameters passed by class factory.
      support of pickling.
cons) It is necessary use factory and line with registration of module.
      For access to specific class version is necessary to use class
      manager.

usage:
  from versionable_class import Manager, factory, VersionableClass
  #register module to class manager. Necessary for pickling.
  man = Manager(__name__)

  class VM1(object):
    @classmethod
    def _is_right_ver(cls, version):
        return True

    def __init__(self, *args, **kargs):
        super(VM1, self).__init__(*args, **kargs)

    def fn1(self):
        print "fn1_VM1"

class VM_container(test_vers.VersionableClass):
    __master__ = VM1

o = test_vers.factory(VM_container)   # return class
o = o()    # create instance of class
o.fn1()

Already used by openvswitch.
