[Twisted-Python] Coil command-line app

[Itamar Shtull-Trauring]

Hi all,

I will soon be writing a coil command line app. It will let you edit an 
exisiting .tap. Ports it creates will not be activated, and its own 
webserver  won't show up in the config interface since it will be 
configuring a different Application insatnce. This will very likely 
replace "mktap coil" for most uses.

It'll working something like this:

$ coil exisiting.tap  (config an existing tap)

$ coil -n "email-server" email.tap (create a new application instance 
and store it in tap)

Any suggestions for possible functionality?
