nnForge v1.0.6

I've just published v1.0.6 release of nnForge. It contains:

• Dropout support is extended to all layers
• Data transformers simplified; removed deterministic mode of noise
• Added sanity check for mse in order to drop ANNs with broken weights during training
• Fixed plain (CPU) backend for rectangular convolutional and subsampling layers
• CUDA exceptions now go with filename and line number
• Minor fixes and improvements
