automatically detect and copy otr_keystore.ofcaes to Android device on Windows
libmtp and direct file copy are not viable options on Windows, so we need to find another way to automatically detect if an Android device is connected, and if so, copy
otr_keystore.ofcaes to it. wmdlib might be a potential option, or perhaps some method in
explorer.exe to copy to the MTP shares that are visible there.
