Logging to loggly over UDP.

Since there were some problems with Loggly, i fixed the following:

- [x] Send Loggly messages over UDP
- [x] Send Loggly messages as JSON over UDP
- [x] Include process ID, to easily group log messages. json.Pid
- [x] Use curl for https messages
This will change the return value from string to an object. Is this on purpose?
