#91 Add DeleteSlot to sqrat::object

[bluehazzard]

It would be nice to have the function DeleteSlot in the Object class

~~~~~

virtual bool DeleteSlot(SQInteger index)
{
    if(GetType() != OT_TABLE)
        return false;

    sq_pushobject(vm, GetObject());
    sq_pushinteger(vm, index);
    sq_deleteslot(vm,-2,false);
    return true;
}

virtual bool DeleteSlot(const SQChar* slot)
{
    if(GetType() != OT_TABLE)
        return false;

    sq_pushobject(vm, GetObject());
    sq_pushstring(vm, slot,-1);
    sq_deleteslot(vm,-2,false);
    return true;
}

a sq_pop is missing at the end of the functions...
