python 3.x (3.5) compatibility

[tyler274]

Lot's of prints without parenthesis for example which cause issues. also dependencies which are part of the standard library and shouldn't need to be declared (argparse, wsgiref.)

the requirements.txt file is autogenerated by pip, im not personally using argparse and wsgiref in my code, but i think libraries i am using need them, and i guess, i should start using print as a function, i cant hide from the future much longer, i guess its time to start working on py3x compatibility
