sub problems were solved:
- sicsget was not reporting geterrors on nodes properly
- rwpuffer contained dirt after wrap
- property change events were added to hipadaba
- Some tuning of SICS output
- The number of codes was wrong in outcode.c
- Allowed write buffers to become very large in asynnet. Thus in order to allow for the transfer
of large images. tested ub to 2kx2k, 16MB
- Handle lack of space in the write buffer more gracefully: just skip the image
