1.3.3 leaks Deflate resource on Android

[gregkorossy]

Calling zipFile.addStream(inputStream, zipParameters) calls zipEngine.addStreamToZip(...) which creates a ZipOutputStream which is a DeflaterOutputStream that has a Deflate member. This Deflate member should be closed using the end() method which is never called.

This has issue has also been found on 1.3.2 and 1.3.3 on createZipFileFromFolder(...), addFolder(...), addFiles(....)

Stack trace from 1.3.3 with Strict mode enable with detectLeakedClosableObjects() turned on:

E/StrictMode: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.
