Update for 3.4.18

Changed paths:
   M /branches/book2ndEd-branch/weka/src/main/java/weka/experiment/InstanceQuery.java

Now uses ResultSetMetaData.getColumnLabel() rather than getColumnName() so that SQL queries using the "AS" clause are handled correctly.

Now prunes generated rule sets according to the upper bound on the support (if < 1). Previously was pruning large item sets of each subsequently larger size according to the upper bound which is somewhat counterintuitive.

   M /branches/book2ndEd-branch/weka/src/main/java/weka/classifiers/functions/MultilayerPerceptron.java

Fixed a bug whereby the ZeroR model is always printed in the toString() method rather than the actual MLP that has been learned.

Added "No class" to the class combo box. This allows principal components access to all the attributes if there is no class in the data. Previously, you were forced to have a class set, meaning that this attribute would always be omitted from the PCA.

   M /branches/book2ndEd-branch/weka/src/main/java/weka/filters/unsupervised/attribute/StringToNominal.java

Was not doing the right thing at all when run in batch mode. String values in the second batch of instances that occurred in the first batch were not being assigned the right index in the converted nominal attribute - fixed.

Updated globalInfo() method and javadoc.

writeBatch() is now more efficient by first writing the header and then one row at a time to disk instead of creating a string of the complete dataset in memory and then writing this string to disk

Improved the output to explain the ranking (both forward and backward) produced when the ranked list option is turned on.
