Add a "Save As" feature to the TCP Follow dialogue, to save the stream

Browse Source 
file to a user-specified file.

Move the file-copy routine in save_cap_file() to an indepenent
function in file.c  (copy_binary_file()) so that follow_dlg.c can use it.

Remove #include "follow.h" from the C files that don't need it.
