Mechanical Turk workflow minor problems

[callison-burch]

In admin/mturk_manager/taskconfig/ the "reward per assignment" field has a max value of $0.99.

After running ./manage.py translate_mturk or ./manage.py mturk_pending_queue the articles should be removed from the Translation Request queue and put into a separate queue, so that the uploaded articles won't be resubmitted if we request translations of additional articles and then run the commands again.

If we can get boto to return the groupID for the HITs, that would allow us to preview them on the mturk web site. I.e. https://www.mturk.com/mturk/preview?groupId=D0FZ2M0F0X68RWCW32TZ

We need to add keywords to HITs through the API. This is how Turkers search for what to do.
