General handling for warnings
As seen in #31 (closed) it would be nice if we can display or log warnings. In this case I discovered that problem only because I ran debug with the new verbose-debug mode. That is optimal, as warnings may useful as well for the developers. Additionally, if we are handling warnings better, we can make unit tests fail as well.
What's better, displaying or logging warnings? And at which place to we want to catch them? Each function or maybe httpRequest? httpRequest has the problem of different formats, if old functions are using format=php, httpRequest can't search for the json part. Or implement an extra function for that?
