Added Hortonworks support for Makefile
First work on maxout/dropout. Still need to handle the dropout from the input layer.
Changed to use dropout_fprop, added dropout option to Eval and Correct. Need to find where to set dropout to true for training. Also need to implement dropout_fprop for the input.
Added temporary fixes to avoid recent bug with flooding  the system with too many Task put keys (implicitly removing *.automframe key on any key insert).

Increased buffer size when uncompressing during parse to avoid problems with a line not-fitting into the combined buffer.
Test split.
Small utilities.
Shuffle task to randomize a vector.

Shuffle is dummy and permutates only data inside the chunk.
Uncommented(for now) previously commented out hook in DKV to remove .autoframe keys as it makes the tests fail.
NN and LaunchJar fixes
Refined the hook in DKV removing auto frames to only apply if we're replacing/removing ValueArray. So that the tests pass and we should not be creating unnecessarily DKV.removes.
