Show "Created by" read-only field in Document Edit view. Update size of TinyMCE widget in Document Edit/Create views. Change user property name to founder in Document model and update files according to this change (now founder is used in Group and Document models). Remove not used variables and imports in views/site/docs/edit.py. Refactor EditForm and CreateForm in views/site/docs/edit.py so that EditForm inherits from CreateForm and just extends it.

    '''
    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.
