Removed Commons IO, which we were only using as a replacement for
File.getFreeSpace() on desktop plaftorms.
Note: The Huawei U8210 (Android 2.1) doesn't have all the Java 1.6
standard library methods, and crashes if they're called. Specifically,
String.isEmpty() and NetworkInterface.supportsMulticast() are missing,
so the changes removing those methods were not reverted.
