feature request: make adding new scopes/types easier

[SKalt]

When I want to enter a new commit-type or scope, I have to

• remember what the new item was called
• write out the new item in the appropriate place in the configuration document.

I'd like to

• have the new item copied to my clipboard so that I don't have to remember it
• if possible, place my cursor at the appropriate location within the config document
• if possible, place a template entry for the new item within the config document at the right location

resolved in adcb96c: now, git-cc copies the new scope to your clipboard (if such functionality is available)!
