v0.2 - Bug fixes and shutdown behavior improvements

This release of Pushy improves shutdown behavior and fixes a number of bugs.

New features and improvements

• Shut down connections by sending a known-bad notification; this significantly increases our confidence about which notifications have been processed by the APNs gateway and which haven't (#4)
• Significantly reduced the number of threads used by Pushy (#9, #13)
• Simplified rejected notification handling
• Made logging generally more robust

Bug fixes

• Fixed an issue where any exception could cause client threads to terminate unexpectedly (#5)
• Fixed a race condition where rejection notifications from the APNs gateway could be lost (#6)
• Fixed an issue where shutting down immediately after starting could throw a NullPointerException (#8)
• Added a read timeout to the feedback client, which resolves an issue where the APNs feedback service is never actually guaranteed to close the connection (#15)
• Fixed a rare NullPointerException that could sometimes occur if a connection attempt succeeded, but a TLS handshake failed (#27)
• Fixed a bug where rejected notification listeners could be incorrectly removed from the listener pool

v0.1.1 - Now with more Maven

While there are no functional changes in this update, we've made some infrastructural upgrades:

• Project is now available via the Maven central repository
• Updated to Netty 4.0.7
• Dropped slf4j-simple as a dependency (it should be up to Pushy users which slf4j implementation they want to use)
