Added h2o.confusionMatrix function for building CM for arbitrary models and predictions
Merge branch 'master' of https://github.com/0xdata/h2o
Moved all tests with fvec and exec in their name, to testdir_single/multi/hosts dir with '_fvec" suffix.
jacobi is defined to be a VA-only, in terms of no-bugs. This means current jenkins jobs won't run fvec stuff (at ec2) with the current jobs you know and love. If these want to be run, michal can easily add fvec jobs that run them. The # of tests was getting unwieldly anyhow for visual tracking so this helps. Will reduce run times also. Why rerun fvec tests if you want fast VA-only results? Also vice versa for fvec. Jenkins 192.168.1.164 jobs are currently just VA, the fvec variants are there but the runner.sh's run the VA variants only.. Should see a shorted list of tests run in tonight's nightly.
get rid of some C0 col specs that still seemed to exist
copy a va + GBM mnist back to testdir_single_jvm
Tweaks to harness:
  *Improved cloud building
  *Match changes to recent JSON changes in GLMVA
  *Fully transactional and when a transaction fails, a message is logged to the appropriate table

load R.utils in runnerSetupPackage (don't take chances)
Add an assert to help track PUB-43
test_rf_VA_simple_example.py wasn't a test, renamed
the GBM tests were doing fvec parse and failed. changed to VA parse.

test_GLM_from_import.py had the old '0' col name

moved the PCA tests back into testdir_single_jvm

changed test_parse_header_rows_mismatch.py to import folder rather than put/upload ..still fails, but easier to see it's got the commands to h2o correct

updated R instructions
add a file close() after unzipping the zipped log files from h2o, before looking at the files.
updte to R console instructions
Minor bug fix in Lockables. We allow write-locks without job (job_key == null), however, some of the methods did not expect to see a null and would NPE. Added null check.

sapply in R

For H2O, behaves like apply(frame,2,function)

Fix for PUB-191. Need to explicitly call uname -p in the shell.
Test for sapply
