Title: Set a default `input_encoding` of UTF-8 when initializing.

This is a new, required option for the latest version of `premailer`. They are yet to release a new version of the gem (annoying) but the changes allow you to set an encoding which helps address several encoding-related bugs (e.g. https://github.com/alexdunae/premailer/issues/92)

For those not using the edge version, I believe the config option will be silently ignored.
