once can't remove handler

[Quard]

Do not work removing handler from event after call

>>> from pyee import Event_emitter
>>> ee = Event_emitter()
>>> @ee.once('event1')
def e1_handler():
    print 'Event 1'

>>> ee.emit('event1')
Event 1
Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    ee.emit('event1')
  File "/home/quard/src/pyee/pyee/__init__.py", line 37, in emit
    fxn(*args)
  File "/home/quard/src/pyee/pyee/__init__.py", line 43, in g
    self.remove(self,event)
AttributeError: 'Event_emitter' object has no attribute 'remove'

Hmm, I see! Very interesting. I thought I tested that!

I'll see if I can fix this today.

Luckily, it seems like a pretty obvious bug, as I was calling .remove instead of .remove_listener. This bug seems fixed in v0.0.2.

The more interesting bug seems to be that the test was passing despite the code obviously being wrong. This is posted as a separate issue.

Go ahead and try out v0.0.2 and let me know if it still fails, so that I may close this issue.

Yet another update: Rewrote the tests, found some more bugs in .once. Should be fixed in v0.0.3, and verified in tests.

I feel pretty good about this one. If you still have issues, lemme know.
