fix the rng seed for caffe (not just numpy); option to randomize training

### Experiment scripts
Scripts to reproduce the experiments in the paper (*up to stochastic variation*) are provided in `$FRCN_ROOT/experiments/scripts`. Log files for experiments are located in `experiments/logs`.
**Note:** Until recently (commit a566e39), the RNG seed for Caffe was not fixed during training. Now it's fixed, unless `` is called with the `--rand` flag.
Results generated before this commit will have some stochastic variation.
