'Thread' object has no attribute 'isAlive'

Hi!

In "/usr/local/lib/python3.9/site-packages/pattern/web/init.py" we have isAlive() in line 224. Running the asynchronous requests example from pattern web it throws:

Traceback (most recent call last):
File "/Users/eyoshi/Python/Pattern/pattern_web_example.py", line 20, in
while not request.done:
File "/usr/local/lib/python3.9/site-packages/pattern/web/init.py", line 224, in done
return not self._thread.isAlive()
AttributeError: 'Thread' object has no attribute 'isAlive'

isAlive needs to be changed to is_alive() here.
