nnForge v1.1.2

I brushed up parameters for nnForge toolset. I also changed default values for some of them; if you run GTSRB you will probably need to update config file. Here is the full change list:

• Deterministic transformator added for testing and validating
• snapshots are made on ANNs from batch directory
• Toolset parameters changed:
• learning_rate_decay_rate is exposed as a command line parameter
• training_speed parameter renamed to learning_rate, training_speed_degradation is dropped
• training_iteration_count renamed to training_epoch_count
• train command does batch train, batch_train command is removed
• validate and test now work in batch mode, validate_batch and test_batch removed
• mu_increase_factor is set to 1.0 by default
• max_mu set to 1.0 by default
• Bug-fixes
