Update byteorder to 0.5

Introduce features to exclude third-party dependencies:

• "snappy" to exclude dependency on thesnappy crate
• "gzip" to exclude dependency on theflate2 crate
• "security" to exclude dependency on theopenssl crate

• Allow Producer/Consumer/KafkaClient to communicate with brokers via SSL -@Hoverbear

This release only slightly changes the public API of kafka-rust compared to 0.2.0.

• Producer will now dispatch messages with the same key to the same partition.
• One publicunsafe method has been dropped from the fetch response structure..
• KafkaClient::fetch_messages guarantees to deliver messages withmessage.offset >= partition.requested-offset (this guarantee was previously available only throughConsumer.)
• KafkaClient::fetch_messages andConsumer will now validate the CRC checksum of fetched messages by default. Since this involves some non-trivial overhead, CRC validation can be turned off.
