Title: Proxy urls should have explicit schemes.

This is for 2.0, and is in response to @t-8ch's suggestion that proxies should have explicit schemes instead of guessing (which is stupid).

@sigmavirus24, @kennethreitz: I'm not entirely happy with the validation code being here: let me know if you have a better idea for where it should go.
