Memory leak

[d3roch4]

Memory leak
in RequestHandler.h file: 29 this allocating a Response
and Controller.cpp file: allocating another 113 this Response.
At the end apens one will be deleted causing a memory leak.

My suggestion is to move the Controller method :: serverInternalError the Controller class to RequestHandler class, I'll implentar this and commit on my fork.
