Debugger tweaks:

ADD: Debugger::getTime() now has a 2nd argument which is number of decimal digits (precision) of the returned time. Default: 3.
ADD: Debugger::getClass() can now strip namespace and return raw class name.
ADD: Debugger::getNamespace() that returns a namespace of a class, without the class name itself.
ADD: Debugger::getClass() that returns a path to file where given class is defined.
