Title: Fix harmless but annoying MSVC warnings.

Suppress

catch.hpp(1760) : warning C4512: 'Catch::TagExtracter' : assignment operator could not be generated
catch.hpp(1864) : warning C4512: 'Catch::TagExpressionParser' : assignment operator could not be generated

warnings given by MSVC 9 (and probably other version too) compiler with /W4 switch.

The warnings are given because the compiler can't synthesize the assignment
operators for the classes with members of reference type, so simply explicitly
declare (without defining) these operators ourselves to suppress them.
