Fix for issue #22 for get, post, delete, put, and patch

[garyrob]

This enables the examples at in the docs which contain extra params and headers, such as

from firebase import firebase
firebase = firebase.FirebaseApplication('https://your_storage.firebaseio.com', None)
result = firebase.get('/users/2', None, {'print': 'pretty'}, {'X_FANCY_HEADER': 'VERY FANCY'})
print result
{'2': 'Jane Doe'}

to work properly. In the current Master version of python-firebase, the following error is triggered:

TypeError: get() got multiple values for keyword argument 'connection'

Hi, Im getting the same error:

TypeError: get() got multiple values for keyword argument 'connection'

from this:
from firebase import firebase
firebase = firebase.FirebaseApplication('https://your_storage.firebaseio.com', None)
result = firebase.get('/users', None, {'print': 'pretty'}, {'X_FANCY_HEADER': 'VERY FANCY'})
print result

or this error if i user /users/2:

File "firebaseconnect.py", line 12, in
result = firebase.get('/users/2', None)

I installed from "pip" a few days ago, had the same error and edit in the file "firebase.py" the commit mentioned above in #25 -> 7b1e5df
