Berkeleyaligner to print progress to terminal

[lewismc]

Right now when testing Joshua from within the Homebrew recipe, a lot of time is being spent on word alignment(???), I think that it would be more helpful if we could see some activity whilst waiting e.g. a progress bar.

The final line above is the one taking a good while!

You can see the output progress for the Berkeley aligner in alignments/NUM/log, where NUM is the alignment shard (default size 1,000,000 sentences).
