aws-verify 0.1.0

Now with reasonable test coverage! 🎉

• Upgraded build to Golang 1.7 for httptest support.

Minor/Internal Improvements

• Intentional panics only happen in main.main. All other functions now return errors which are checked for in main.main.
• Use pem.Decode correctly. Have to check for return == nil before trying to feed the return value to x509 and pkcs7 methods, which will otherwise promptly panic if their input is not a byte array.
• LINT ALL OF THE THINGS
