Update org bulk accept script. The script now: 1) leaves correctly control to the browser to update the GUI of the progress bar during ajax communication. 2) Displays an error if something went wrong (I've tried in my box stopping the server while doing the requests), and show a retry button to fetch again the list of the applications that are still not accepted and iterate over them again (seems to recover correctly restarting the server after the error in my box) 3) doesn't display any text at the beginning, and the button has the correct CSS class assigned 4) Check if there are applications to accept, if not displays a message stating that there are no orgs to accept.

    '''
    Handler that uses hotshot to store profile data.

    Stores profile data in PROFILE_DATA_DIR.  Since hotshot has no way (that I
    know of) to append profile data to a single file, each request gets its own
    profile.  The file names are in the format <url>.<n>.prof where <url> is
    the request path with "/" replaced by ".", and <n> is a timestamp with
    microseconds to prevent overwriting files.

    Use the gather_profile_stats.py script to gather these individual request
    profiles into aggregated profiles by request path.
