This is a standalone version of the collabwrapper.  You can make
collabwrapper.py importable by your activity, and then use a try/catch
for the import, eg:

    try:
        from sugar3.presence.wrapper import CollabWrapper
        from sugar3.presence.filetransfer import FT_STATE_COMPLETED
    except ImportError:
        from collabwrapper import CollabWrapper

You can then use CollabWrapper and the filetransfer module normally.
