This patch attempts to solve the Python 2 / Python 3 incompatibilities by introducing a new `encoded_file` abstraction that we use instead of `io.open()`. The problem with the builtin implementation of `io.open` is that `read` and `write` accept and return `unicode` objects, which are not always convenient to work with in Python 2. We solve this by making `encoded_file.open()` return the same object returned by `io.open()` but with hooked `read()` and `write()` methods. These hooked methods will accept binary or text data, and conditionally convert what it gets to a `unicode` object using the correct encoding. When calling `read()` it also does any conversion necessary to convert the output back into the native `string` type of the running python version.
