Hey thats neet. Do you mind if i apply thoses change on my fork ? I needed to switch to python 3 too

I tried to run the Katoolin master version on my computer and it doesn't work due to the Python version problem. My computer only has Python v3 installed, so I thought that would be the worst decision to install old version of Python only to run Katoolin. I changed the code for compatibility with Python 3. So when I come to pull requests to suggest this change on the Katoolin code, I noticed that there are at least other two pull requests solving this compatibility problem with at least more than 6 months opened! Until now the maintainers did not consider applying those fixes! Why have those simple changes weren't been applied to the master version?
I considered the possibility that the maintainer had died...
Will we have to create a fork version to apply those important changes?

@JackSparrow0723 I noticed that has passed more than 1 year of this pull request and those important fixes wasn't been applied. It seems that this project is abandoned. So, I decided to create a fork version of this project for receiving all fixes and improvements... if the maintainer in near future decides to bring the changes, its ok, but until this would be better for community work under a new fork that I created of this project:
https://github.com/tarciziovn/katoolin

I applied your suggestion of parenthesis to my own fok of the project, but I'm using other suggestion of using the lib past.builtins importing raw_input function for compatibility on Python 2 and 3.
