Python 3 binding

Has anybody used libinjection with python 3.5? I didn't find any info about python 3 support. I built libinjection python version with -py3 swig option and got the module:

```
# pip3 show libinjection
---
Metadata-Version: 1.1
Name: libinjection
Version: 3.9.1
Summary: Wrapper around libinjection c-code to detect sqli

I can import the module without errors, but I can't use libinjection functions (from the [docs](https://github.com/client9/libinjection/wiki/doc-sqli-python)):

```
Python 3.5.1+ (default, Mar 30 2016, 22:46:26)
[GCC 5.3.1 20160330] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from libinjection import *
>>> sqli_state()
Traceback (most recent call last):
File "", line 1, in
NameError: name 'sqli_state' is not defined
```

The same code works well on python 2.7

```
Python 2.7.11+ (default, Apr 17 2016, 14:00:29)
[GCC 5.3.1 20160413] on linux2

>>> from libinjection import *
>>> sqli_state()

```

It will be really great if somebody can help me with this question. Thanks!
