batch filtering didn't set the correct dataset for instances of the second dataset before getting passed through the filter, resulting in a dataset with class index -1, even though the class index was set via the '-c' option. this can result in a "headers don't match" exception (e.g., AttributeSelection filter in combination with PCA)

added merge functionality to commandline: weka.core.Instances merge <file1> <file2>
uses now DataSource to read any data format instead of only ARFF format

• core/Instances.html (1.67)

the mergeInstance method produced corrupt results or NullPointerException in case the datasets had different number of attributes
thanks to Scott Davies

• core/SparseInstance.html (1.17)

fixed NullPointerExceptions if no file extension was provided explicitely

• gui/ConverterFileChooser.html (1.6)
