v0.4.2 - New payload fields, improved handling for bogus sequence numbers

This release includes updates to handle a couple upstream changes:

• Added support for the title, title-loc-key, and title-loc-args introduced in iOS 8.2 (#148—thanks, @matzew!)
• Added a workaround for new upstream behavior where the APNs gateway will incorrectly send a sequence number of 0 when receiving a malformed notification like the one we use to close connections (#152—thanks, @U-238!)

Additionally, Pushy now depends on Netty 4.0.25, the latest release at the time of writing, to take advantage of upstream improvements and bug fixes (#147—thanks again, @matzew!).

For additional details, please see the v0.4.2 milestone.
