The tool's source was updated several times, but the APK was
never updated. This change brings the APK to the master
commit, and updates the 'build.gradle' to build using the API
22 build tools (was using API 20, but that is obsolete now).
The XposedBridgeApi.jar library has been updated to utilize new
functionality. The commit for the WebView checks was not
implemented correctly, and resulted in exceptions when attempting
to hook any application. The code was also missing functionality
to disable all validation for the Apache libraries.
