Test that DropoutLayer obeys dropout_ratio
Add script to speedtest imagenet (currently broken as FilterNet ignores
Caffe::phase()).
Add tests for phase filtering according to Caffe singleton phase

Fix speedtest (and possibly other tools) by setting the net phase to the
current Caffe::phase() unless explicitly specified in the state.
