This release is primarily a testing/code coverage release, with some minor features.

Went from ~70% to ~96% test coverage.

Minor features:

• Proper HEAD support
• Support more of net/http's interfaces: Hijacker, CloseNotifier, Flusher
• Pluggable loggers for the LoggerMiddlware and the PanicNotifier.

NOTE: Some types had their exportedness changed to private, so this release does have some minor backwards incompatibility if you happened to be using those types (there was no reason to).

Version 1.

Tagging the release for gopkg.in.
