Subject: Include/cppunit/Protector.

include/cppunit/Protector.h:
* src/cppunit/Protector.cpp: added. Base class for protectors.

* src/cppunit/DefaultProtector.h:
* src/cppunit/DefaultProtector.cpp: added. Implementation of the default
protector used to catch std::exception and any other exception.

* src/cppunit/ProtectorChain.h:
* src/cppunit/ProtectorChain.cpp: added. Implementation of a chain of
protector, allowing catching custom exception and implementation of
expected exception.

* src/cppunit/TestCase.cpp:
* src/cppunit/TestResult.cpp: updated to use protector.
