Eike Rathke fcd0361d6b Eliminate Date::operator+=() and -=() and replace with Date::AddDays()
Clarifies code and gets rid of explicitly casting the operand to sal_Int32.

Also in preparation of removing DateTime::operator+=(sal_Int32) that is
confusingly similar to DateTime::operator+=(double) and just depends on type.
