#128 TiXmlString& operator=(const char *) exceptions on NULL

[Sean]

TiXmlString's '=' operator (char*) will crash on NULL values. For example:

TiXmlString str;
str = NULL;

Since TiXmlString has its own 'null' representation, shouldn't this use that in this case? I.E.:

TiXmlString& operator = (const char * copy)
{
if(copy == NULL) // handle null string cases
{
clear();
return *this;
}

return assign( copy, (size_type)strlen(copy));
}

[Sean]

The two "TIXML_EXPLICIT TiXmlString (const char *)" ctors would also need this handling if this is indeed invalid behavior.
