[TYPO3-mvc] Fetching FEUsers related to FEUserGroup

[Alex Bailey]

I fix'd it by adding the following to the Typo3DbBackend.php line 546

$statement .= ' OR ' . $tableName . '.' . $operand1->getPropertyName() 
. ' LIKE \'' . $this->getPlainValue($operand2) . '\')';

This checks if the operand contains a single value.
I don't know if thats the best way to solve it right now but it works 
fine for me.
Thanks Franz for the great help would neverhave thought about looking 
there (working to long on that problem already)

Regards,

Alex
