sw: Help vs 2015 with virtual base inheritance

MSVC 14.0 was failing to compile IMark class an friends with:
error C2280: 'SwModify &SwModify::operator =(const SwModify &)':
attempting to reference a deleted function: [1].

After defining copy ctor and assignment operator in SwModify and
derived classes as deleted the next failure was:

error C2512: 'sw::mark::IMark::IMark': no appropriate default
constructor available: [2].

Defining default ctor as default in IMark and derived classes
seems to make all compilers happy.
