Title: Removed strtolower() when preparing URL.

Some providers, like LinkedIn, uses a case-sensitive URL which includes capital letters.

Some examples:
https://api.linkedin.com/uas/oauth/requestToken
https://api.linkedin.com/uas/oauth/accessToken

Reference: https://developer.linkedin.com/documents/linkedins-oauth-details
