Added moveFile()
* HttpStatusCodeException - Removed IOException's Throwable argument as
it is incompatible with older versions of Android (< API Level 9), and
never used.
* HttpStatusCodeException - Cleaner message to IOException.. If HTTP
Status Message & server response are redundant (eg. both start with the
word "Forbidden"), the constructor will remove the duplicate wording.
* HttpUtils - some variables renamed.
* Updated eclipse project files
* Added Base64 (moved from AOSUtilsAndroid) for encoding/decoding
Base64. This is taken straight from AOSP (Android Open Source Project)
