There's a number of instances of os.path.join used when working with directories on the mobile devices. However, this causes issues on Windows hosts, where the path separator is different than the *nix-based iOS/Android device we're connected to. This has caused a number of issues, including #165 and #197.

Realistically, we should be determining the proper path separator for the device (right now, it's only /, but what if this was extended to UWP apps or something), and storing that at the device level, as well as a method to join these paths properly. Then, when attempting to do os.path.join calls, drop that method in as a replacement.
