Release 0.3.1

Added support for WePay-Risk-Token and Client-IP headers on all API calls (see: https://developer.wepay.com/reference/risk_headers).

Release 0.2.7

Added support for user_country to getAuthorizationUri()'s options param.

Fix all the typos!

Fixed a few more latent bugs, and manually tested the demo apps.

Some love.

This SDK hasn't had much love in a while. We accepted some pull requests and reformatted the code to follow PSR-1/2.
