pysignal's Issues

AttributeError: 'ClassSignalFactory' object has no attribute 'register'

With python 3.6 using the following code:

from PySignal import *

def greet(name):
    print("Hello,", name)

class Foo(object):
    started = ClassSignal()
    classSignalFactory = ClassSignalFactory()
    classSignalFactory.register('Greet') #Causes an error
    
    def __init__(self):
        super(Foo, self).__init__()
        self.started.connect(greet)
        self.started.emit('Watson')

        self.signalFactory = SignalFactory()
        self.signalFactory.register('Greet')
        self.signalFactory['Greet'].connect(greet)
        self.signalFactory['Greet'].emit('Sherlock')
         
        self.classSignalFactory['Greet'].connect(greet)
        self.classSignalFactory['Greet'].emit('Moriarty')
        
        ended = Signal()
        ended.connect(greet)
        ended.emit('Mycroft')

foo = Foo()

TypeError raise by WeakMethod not handled.

Just realized that WeakMethod (including backport) raises a TypeError that isn't currently handled.

Threading support, queued Signal connections

Firstly, this project is super cool, thanks for tackling this!

Looking through your tests and code, I don't see much in regards to threading support, or implications of using signals for thread communication. At least in Qt, I see that as a major feature of Signals and Slots. The ability to send a signal/message to a thread and have that message queue is a pretty awesome feature. While I don't see explicit support for this, it's possible that "it just works." If that's the case, it would be great to see some examples of it's usage in a threading context.
