K-skip ngrams for quadratic support in HashedDoc classes
update news
Using the same CRandom instance over multiple threads is not safe.  Modified
StratifiedCrossValidationSplitting so that we can set own RNGs using member
m_rng.
Added additional permute methods to SGVector which take external random state.
Added external random state changes to CrossValidationSplitting as well.
Added shuffle(CRandom*) methods to DynArray, DynamicArray and DynamicObjectArray for thread safe shuffling.  (e.g. parallel cross validation)
Cleaned code duplication introduced by earlier commits.  Now using ->shuffle(m_rng) for shuffling arrays.
Add cmdline_static interface
Add PytonStatic interface
Add RStatic interface
Add OctaveStatic interface
fix RStatic library
Merge pull request #1424 from tklein23/thread_safe_xvalidation

Setting RNG in StratifiedCrossValidationSplitting for thread safety
Rename cmdline_static target
Add or fix get_name function for the classes in the patch
Add --only-on-failure command line argument for unit tests
With --only-on-failure only failing unit tests are printed and the unit
test summary on the end. By default it's disabled.
