Felix Bünemann 7a4b8bb048 Fix high memory usage due to Deflater buffering 
When support for ZipCrypto was added, an internal StringIO buffer was
added to Deflater, in order to fix a decryption bug. While this worked,
it caused unlimited memory growth when compressing large files. The
proper fix is to writer the encryption header in init_next_entry instead
of finalize_current_entry, so the headers are written before any
encrypted data. Because of this fix we can remove the buffering in
Deflater, which keeps memory usage low and allows to stream compressed
data while it is written.

This should fix issue #233.
