Cancel connection before deallocation.
Travis CI file
Updated README.md with Travis CI image

Note: Change the icon image to point to the master branch when merging
Fixed proper naming convention and payload init
Initial tests for SnowplowPayload
More tests for SnowplowPayload
Changed addJsonToPayload to void method
Outputs any error to the log, then returns out. This can be done better to let the caller know if there was a success or failure.
Fixed addJsonToPayload to encode the NSData object directly
 - Removed 3PD lib for base64encoding to use deprecated native library
(iOS 7 and lower)
 - Added addJsonStringToPayload for ease-of-use in the future (can be
removed if needed)
More tests for addJsonToPayload & addJsonStringToPayload
Specifically, tests for b64 encoding/decoding
Removed unnecessary b64 dependency
Now relying solely on native lib for everything
SnowplowUtils for getting user profile info
Reversed keys and values in init
Tests for SnowplowUtils
Updated .travis.yml
Updated .travis.yml (again)
