Python 3 has a different syntax for imports

[jvazquez]

I'm testing your code using python 3.5.1

I forked your project, but noticed that you have an open pull request that fixes this situation

#3

`
Python 3.5.1 (default, May 1 2016, 12:06:57)
[GCC 5.2.1 20151010] on linux
Type "help", "copyright", "credits" or "license" for more information.

from awses.connection import AWSConnection
Traceback (most recent call last):
File "", line 1, in
File "/home/jvazquez/.pyenv/versions/msaas_profile/lib/python3.5/site-packages/awses/connection.py", line 2, in
from signer import ESConnection
ImportError: No module named 'signer'
`

Would it be possible to accept that pr ?

Though, one change that it could be applied on the PR3 is the import of urlparse

is

try:
    from urllib.parse import urlparse
except ImportError:
   from urlparse import urlparse
