Bandwidth by IP - new Bw from and to headings

Now that the BW by IP table shows data for IP addresses at both ends of a transmission, the "In" and "Out" labels are only right for 50% of the rows. Actually the table is showing the BW coming from each IP and the BW going to each IP. Confusion should be cleared up by renaming the column headings and sort dropdown labels. I bit the bullet and changed all the "In" and "Out" var names to "From" and "To" also to make the code readable and replaced multiple spaces with tabs at the beginning of lines.
