Remaining calls to exit

[Juan Manuel Palacios]

	Good afternoon everyone!

	I'll be releasing 1.5.1 real soon now and I'm planning on including  
Landon's commit that hides the exit routine from the Portfile  
interpreter, causing the keyword not to be recognized; therefore  
remaining calls to it should be removed from the Portfiles. Following  
is a list of ports that still have it:

  * aqua/TeXShop
  * editors/xemacs
  * graphics/graphviz-cairo (safe to remove?)
  * java/tomcat5
  * lang/clisp
  * lang/ghc
  * lang/hugs98
  * math/GiNaC
  * math/cln
  * math/nestedsums
  * multimedia/mimms
  * net/djbdns
  * net/kerberos5 (commented out, though)
  * science/xloops
  * science/ophcrack
  * sysutils/ipc
  * www/mozilla-devel
  * www/mozilla
  * x11/gtk2
  * x11/gtk28
  * x11/xorg

	Would love it if maintainers could update their ports to match the  
upcoming released code base. Thanks in advance for your help!

	Regards,...
