setup.py needs to specify encoding when reading README.rst

[andrewmwilson]

I've found another issue with the recent changes to setup.py (2e5031b)

Depending on the current locale, installation fails when setup.py attempts to read README.rst

Sorry to do this to you @jadchaar!

No problem @andrewmwilson thanks for bringing this up. Hah the seemingly innocuous change seemed to cause the most issues.

@andrewmwilson arrow 0.14.2 has been released to address this issue. Let us know if it fixes the issue and if you have anymore questions or concerns!

[andrewmwilson]

Thanks again!
