Update PyPI Release / Readthedocs

[hydrosquall]

Hi @jreback / @davidastephens / anyone with push access:

Would it be possible to cut a new 0.6.0 release to PyPI, or bump the current version to 0.5.1 so that the ReadTheDocs documentation can be updated? This is because the old usage directions for EnigmaDataReader no longer apply.

The PR #380 was merged last month into the current 0.5.0 build, but the (unreleased) docs reference the 0.6.0 build as directed in the PR. https://github.com/pydata/pandas-datareader/blame/master/docs/source/remote_data.rst#L210

This mismatch may contribute to confusion for other issues such as #406 .

I would also be interested in a new release, since #404 fixes the following code, which doesn't work in 0.5.0:

import pandas_datareader.data as web

print web.DataReader('SPY', 'google')
