Enhance handling of parameter lists when creating dimension bundles

[GoogleCodeExporter]

When trying to create a dimension bundle with a list of bundles
List<Map<String, Object>> listOfBundles = new ArrayList<Map<String,Object>>();
and calling toArray() on the list
Dimension.createBundle(NAME, listOfBundles.toArray());
an Object[] array is created causing the following exception:
Exception in thread "main" java.lang.ClassCastException: java.util.HashMap 
cannot be cast to java.lang.String
       at de.tudarmstadt.ukp.dkpro.lab.task.impl.DimensionBundle.<init>(DimensionBundle.java:54)
       at de.tudarmstadt.ukp.dkpro.lab.task.Dimension.createBundle(Dimension.java:103)

The lab could check whether the Object[] actually contains the expected 
Map<String, Object> and convert accordingly.
