v0.5.1

• Fix model.modelload() when using the new Conv constructor with optional pool_shape. Loading models from .mdl files was broken in 0.5.0 (#13, c2a7b8a)
• Better progressbar for model.predict_dense() (thanks @mahsabh, 6ee6d18)
• Extend maximum runtime and iterations of example networks to make sure they can be fully trained (970bfa4, 86fea4c)
