Change Logging class / method name and Debug Support for backtrace

Debug Support:
getCallerClass now returns level 1 class from the trace like the
getCallerMethod. There is also a new getCallerClassMethod that returns
namespace\class->method (or :: for static).

getCallerTopLevelClass works like getCallerClass did before and returns
the TOP level (first entry on the call stack that has a set class name)

Logging:
Do not use the Support getCallerClass/Method/File but call it inside
and use level 2 in trace to get the data we need For the last call
before debug call
Also update the strack trace for the debug call to use ->/:: for method
type
