<p>Checks if a field is forbidden in combination with a given Database (most often because that database
does not implement the features required by the field/value combination). If a "forbidden" use is detected,
a validation error is added to the current list of ValidationErrors.</p>
Note:
<ul>
<li>if value==null, the field is ALLOWED for all DBs</li>
<li>if the disallowedDatabases list does not at least contain 1 entry, the field is NOT allowed</li>
</ul>

@param disallowedFieldName field whose value is checked
@param value               value that might be disallowed
@param database            database the object/value combination is checked against
@param disallowedDatabases a list of "forbidden" databases that do not allow this field/value combination
