Adding vscript GetKeyValue vscript

Browse Source 
Intended usage:
```
int nIterator = -1;
ScriptVariant_t key, value;
while ((nIterator = pScriptVM->GetKeyValue(table, nIterator, &key, &value)) != -1)
{
    printVariant(key);
    Msg("=");
    printVariant(value);
    Msg("\n");

    pScriptVM->ReleaseValue(key);
    pScriptVM->ReleaseValue(value);
}
```
