remove references to using shar archives for submitting ports

[zeising]

Summary

We don't need shar archives to add new ports, remove them from the porters handbook.

Good to go!

Could you maybe keep the example as it is now, and add a second example using shar ?

I'm not entirely sure what you mean. Currently there is one example of how to do a diff, and one on how to do a shar, I've removed the shar example, as well as references to .shar files.

Keep the shar example, but de-emphasize it and put it at the bottom, as suggested by @mat .

Could this be changed to use bsdtar, it feels "safer" than shar, something like:

&prompt.user; <userinput>tar cf <replaceable>oneko</replaceable>.shar --format shar <replaceable>oneko</replaceable></userinput></screen>
