Jet Profiler

------------
* Brand new profiler UI

Jet library (core)
------------
* New class Debug_Profiler_Run_BacktraceItem (extends Debug_ErrorHandler_Error_BacktraceItem)
* Debug_Profiler_Run_BacktraceItem represents all profiler backtraces (and not only simple array)
* Debug_Profiler->getRootDir(): string added
* Debug_Profiler->getBlock( string $id ) : ?Debug_Profiler_Run_Block added
* Jet_MVC: profiler block names simplified

Jet Debug ErrorHandler > Display
------------
* The error handler has the same font as the profiler
