Use nicer mpl default plots about astropy-tutorials

[adrn]

Thanks!

Future Adrian: for context, "I'm punting the matplotlib style stuff until matplotlib 1.4 comes out because the style stuff has now been merged into mpl (matplotlib/matplotlib#2236)."

@adrn can you share your .matplotlibrc in this repository (perhaps as 'default_style'?) so that the notebooks can be reproduced in their current form. When I run the notebooks, the fonts are a little different. There may be other changes, but I can't identify any right now...

[adrn]

@keflavich Oh shoot, right, I have a custom font. Rather than deal with that headache, I think it'd be better for me to just use the MPL defaults for now. Is there any easy way to manage multiple matplotlibrc files? Like, start IPython with a particular rc file? hm..

Yes. matplotlib.rc_file('/path/to/file'). I think including a line of this sort at the top of the ipynb, along with the %matplotlib inline command (I think that's right...) would be good practice.

Ok my plan is to make an ipython profile that makes that call (matplotlib.rc_file('/path/to/default/rcfile) in a startup script so I don't have to add it to all tutorials..

[keflavich]

OK, but it would also be a good solution to this issue to include the "nicer mplrc" file in this repo, and have it included in each ipynb

As they say, "true dat"
