Minor cleanup of GLM2 input and output parameters.  Just cosmetic.
Added max_iter and higher_accuracy glm2 parameters.
Merge branch 'master' of github.com:0xdata/h2o
fix a path dependency issue
add exception printing
2nd try at not adding (so not messing with locks of) unparsed stuff to Exec env
apparently isRawData has to hang off DKV.get()

      if( val.isFrame() ) {
        val = DKV.get(k);       // Fetch the whole thing
        if( val == null ) continue; // Racing delete got it?
->      if( val.isRawData() ) continue; // don't add unparsed stuff

this passes build.sh junit/R tests plus my test
Merge branch 'master' of github.com:0xdata/h2o
prepend the short testdir with the prefix (singlenode multinode)
Update dummy list of all tests to run: remove NeuralNet tests.
add correctness criterion where possible
describe necessary dependencies.
remove try/except for now (need failures to stop the test)
change some println's to Log.info and Log.err
Merge branch 'master' of github.com:0xdata/h2o
minor edit to fix typo
Re-enable deprecated NeuralNet JUnit tests, added deterministic RNG seed for NNIrisTest.

List requirements for building
Minor update in docs.

For building H2O we do not need Scala but only Sbt which
will internally download the right version of Scala and
additional libraries.
