easy way to change print order

[Chris Smith]

Shouldn't there be an easier way to change printer settings than this:

>>> u = parse_expr("-5 + 2*x + 3 - 7*x + 5 - 3*x", evaluate=False); u

-7*x - 3*x + 2*x - 5 + 3 + 5

>>> u.args
(-5, 2*x, 3, -7*x, 5, -3*x)

>>> s=StrPrinter()

>>> s._default_settings['order'] = 'none'  # < -- isn't there a better way?

>>> s._print_Add(u)
-5 + 2*x + 3 - 7*x + 5 - 3*x

The public API would be StrPrinter(dict(order="none")).doprint(u).

But you can also use sstr(u, order='none').
