enabled code analysis in MSVC project Configuration,
did not enable it for the Test project as this results in extremely long build times!
added BOOST_INCL_GUARD_BEGIN and BOOST_INCL_GUARD_END macros to guard boost headers from MSVC code analysis
split ExceptionToString() into two versions, removed unnecessary catch() blocks
