Inconsistent spacing

[kuhoyo2964]

For someone using the program for the first time unmodified, they might encounter the "inconsistent spacing" python error, don't know if this is a python3 thing or if this error started showing up when you brought python3 compatibility.

Fixed easily by accessing the source code with vim and typing in :
--> :%s/^I/ /g <--

:%s///g

This replaces all tabs with 4 spaces.

P.S Great projects, you should really develop it more, I think it's going to get REALLY popular, it's really cool, good job :)
