[Click] NSClick patch for NS-2.34

[Eddie Kohler]

Wim,

Thanks very very much for this!  I've verified that the patch works and 
checked a version of it in.  My version differs from yours in that I ran 
'configure' to make sure the --with-click argument was supported, and 
re-generated the patch so the line numbers are correct.
