ipy.highlighting_style can be a string

[njsmith]

• PrettyPrinter version: 0.8.0

According to https://ipython.readthedocs.io/en/stable/config/details.html#terminal-colors:

TerminalInteractiveShell.highlighting_style determines prompt colours and syntax highlighting. It takes the name (as a string) or class (as a subclass of pygments.style.Style) of a Pygments style, or the special value 'legacy' to pick a style in accordance with InteractiveShell.colors.

(emphasis added). But if I set highlighting_style = "default" in my IPython startup file, and enable prettyprinter integration, then I get a traceback ending in:

~/.user-python3.5-64bit/local/lib/python3.5/site-packages/prettyprinter/color.py in colored_render_to_stream(stream, sdocs, style, newline, separator)
    213                     except KeyError:
    214                         pygments_token = _SYNTAX_TOKEN_TO_PYGMENTS_TOKEN[sdoc.value]
--> 215                         tokenattrs = style.style_for_token(pygments_token)
    216                         color = styleattrs_to_colorful(tokenattrs)
    217                         color_cache[sdoc.value] = color

AttributeError: 'str' object has no attribute 'style_for_token'

I think there's some missing if instance(style, str): style = pygments.styles.get_style_by_name(style)

Thanks! Should be fixed in 0.8.1 that I pushed to PyPi.
