Add another script: 'ghissues-close'

A script that will close a github issue of your choice with a comment

Arguments:

• Github token

• Github username

• Repo

• Use current directory

• Issue ID

• Comment

• If no issue id is provided it will list the current open issues, their IDs, then prompt you to: 'enter an id and hit enter'

• If no comment is provided, it opens EDITOR.

• The editor is populated with:

  • Closing <ISSUE NAME> with [commit](<link to commit>)

Add 'ID' column to ghissues-get

This goes with the new ghissues-close script

It would be nice to have the issue id appear in the get command as well so users can have that information prior to running ghissues-close --id <ID>
