Fixing new API weaving & docs
Merge remote-tracking branch 'origin/master'
Ignore constructors order in Request2
moved from testdir_0xdata_only. Does import folder from /home/0xdiag/datasets/mnist

Merge branch 'master' of github.com:0xdata/h2o
summary and inspect cleanup: add max_column_display parameter, tests
Added ability to set column names of a value array (to column names of another VA with compatible #cols).

Also changed parse page to reflect guessed setup and to allow for single line (including header only) files to parse.
(just missing changes from my previous commit).

Conflicts:
	src/main/java/water/api/Inspect.java
Minor tweak of setup parser setup compatibility check + excluded GBMTest which was failing for me after the last pull.
