Changed paths:

Reduced memory consumption of REPTree by roughly 30 percent. Unfortunately the code is now even uglier than before.

Using a seed < 0 will now cause buildClusterer() to not randomize the data. This will give the same results as the command line (where Cobweb is trained incrementally and randomization can't be done anyway).

Changed paths:
   M /trunk/weka/src/main/java/weka/filters/Filter.java

Added a mayRemoveInstanceAfterFirstBatchDone() method that returns false by default. Some filters may not necessarily be able to produce an instance for output for every instance input after the first batch has been completed, and can override this method to return true. An example is the RemoveWithValues filter - it will consume an instance that matches one of the values that the user wants to remove (even after the first batch is done). FilteredClassifier throws an exception in distributionForInstance if the filter doesn't make a test instance available immediately. It might be better if it is possible to test to see if this is a possibility for the filter in question (rather than a bug) and then return all zeros or NaN to indicate to Evaluation that the test instance is unclassified.

fixed the ClassifierPanel:
- command/scheme output was using the original classifier twice to generate the string, instead of the InputMappedClassifier, resulting in a commandline that could not be executed

Extended readProperties(String) method: it now loads all the properties files from the classpath that have the same resource name, and not just the first one.
This allows applications that use Weka as a library to define their own algorithms/filters/etc. but no longer requires them to place a .props file in the current/home directory in order to expose these classes, for instance in the GOE.
Adding new properties in the props files is unproblematic, but overrding properties is sensitive to the order the ClassLoader returns the resources, of course.
