Fix tuple printing on py2

[KeyWeeUsr]

Don't know about linux/mac, but on win there is this output on garden install <something>:

print(something, something) returns tuple

('Progression', 1024, '|', '\r')
('Progression', 2048, '/', '\r')
('Progression', 3072, '-', '\r')
('Progression', 4096, '\\', '\r')
('Progression', 5120, '|', '\r')
('Progression', 6144, '/', '\r')
('Progression', 7168, '-', '\r')
('Progression', 8192, '\\', '\r')
('Progression', 9216, '|', '\r')

which is fixed by this PR. However, as you can see, \r won't rewrite the line in something like cmd.exe(didn't try with powershell). Is it intended behavior?

Ín my Windows 7 machine the \r character is correctly rewriting the line in CMD.EXE but for that you'd also need to pass an empty string onto the end parameter to the print() function. Or you could alternatively also specify the end argument of the print function as: , end='\r' - see also http://stackoverflow.com/questions/17391437/how-to-use-r-to-print-on-same-line

This is looking a bit complicated. '{} {} {} {}'.format('Progression', count, animation[index % len(animation)], '\r') is probably better.

@AndiEcker Yes I know about that, but print is still a statement in python2, therefore no end= is available. I wanted it to behave in a similar way and support even those old versions such as 2.3.5.

@matham Yup, looked ugly, but the reason is here ↑, anyway I looked into python docs and format is available since 2.6(and there's a lot of format() in garden), so the solution doesn't actually matter, because I can take python function from __future__ instead and it'll work as in py3. ✌️ I added only import from __future__ so that #16 could be merged too as it's already there since May.
