SwiftNIO 1.3.0

Semver Minor

• Gave HTTPResponseStatus a public initializer that can take a numerical status code and optional reason phrase and create an appropriate enum member, instead of forcing users to use .custom. (#158)
• Added EventLoopFuture.hopTo(eventLoop:) to simplify code that needs to ensure callbacks dispatch to a specific thread. (#177)

Semver Patch

• Suppressed compiler warnings that were emitted in release mode. (#179)
• Fixed compilation on iOS. (#180)
