Make "skip_on_exception" a signature-preserving decorator.

[OlegShteynbuk]

Currently skip_on_exception is not a signature-preserving decorator, at least in Python 2.7. When writing tests one needs to use a workaround to parametrize skip_on_exception decorator see #357 for discussion.

run successfully local tests with module wrapt that comes with anaconda and for some reasons, it is not available for Travis CI
https://github.com/GrahamDumpleton/wrapt

It needs to be added here:

https://github.com/pydata/pandas-datareader/blob/master/.travis.yml#L54

to be available on TravisCI.

[bashtage]

Or here

https://github.com/pydata/pandas-datareader/blob/master/.travis.yml#L63

to install via pip

Oh yes! sorry you are right! sorry for noise.

@OlegShteynbuk : Thanks for sharing this library! Good to know that it exists. While I'm still a little uneasy about installing an entire library just for this, I don't see a better way to fix this at the moment. 😄

Could mark a TODO on this to drop this library after 2.7 is dropped (even though this will be a while).
