BioWeka 0.7.0 released

This release contains some important changes and bug fixes:

• We changed the architecture of the alignment packages. The new aligner classes are found in packages which refer to the source of the underlying algorithm code (e.g. bioweka.aligners.jaligner.SmithWatermanGotohAligner).
• The new release solves a problem when using the "supply test set" option with BlastClassifier or SimpleAlignmentClassifier, which lead to incorrect results in previous releases (other options like cross-validation or percentage split were not affected).
• The interface of the BlastParser and the converter classes for sequence-based data formats have been updated.
