If default profile doesn't exist, can't install mathjax to any location

[rgbkrk]

Fresh install of IPython, profile named 'cooked' created.

(ipyvirt)ipynb@ipynb-cookbook-berkshelf:~$ python -m IPython.external.mathjax --install-dir .ipython/profile_cooked/static/mathjax

    raise IOError("Couldn't find profile %r" % profile)
IOError: Couldn't find profile 'default'

This is largely due to the global variables set at the start of IPython/external/mathjax.py.

static = os.path.join(locate_profile('default'), 'static')
default_dest = os.path.join(static, 'mathjax')

Just ran into this myself on a fresh Ubuntu 13.04 AMI.

Should be fixed by #4277.
