Make the ToS text in-line and hook up thick-box in the help-text. This way the user can see the ToS in scrollable form between the link_id and the 'agree to tos' checkbox. Also, when clicking on the link to the 'side-wide terms of service' a thickbox will pop up and display the Terms of Service in an overlay. Patch by: "Mario Ferraro" <fadinlight@gmail.com>

    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.
