Change output filenames in replication scripts

[jbueltemeier]

As mentioned in #275 the output file names are not yet ideal. This PR addresses this problem by making the file names more consistent. They now essentially consist of three components.

1. The name of the replication.
2. Additional parameters that are important for the name (figure labels, hyperparameters, ...).
3. An optional flag indicating whether the impl_params are used.

Example of current filename: "_gatys_ecker_betghe_2016__fig_2Bimplparams.jpg"
