Issue on Python 3.4.1

I'm experiencing the following issue when using gignore on python 3.4.1:

```
$ gignore JetBrains
Traceback (most recent call last):
File "c:\Python34\Scripts\gignore-script.py", line 9, in
load_entry_point('gignore==2014.10.28', 'console_scripts', 'gignore')()
File "C:\Python34\lib\site-packages\gignore\cli.py", line 33, in main
wrapwrite("{0}\n".format('\n'.join(gig.get_errors())))
File "C:\Python34\lib\site-packages\gignore\utils.py", line 11, in wrapwrite
sys.stdout.buffer.write(text)
TypeError: 'str' does not support the buffer interface
```
