if create template is not saved, consider the create aborted

[jaybuff]

If I run "jira create" then do not save my changes, the client should not attempt to POST to jira or offer me the option to edit again.

Right now, I get this output after I do ":q!" in vi:

edit again? [Y/n]: n

yeah, we can try this approach, it will not work with some editors that auto-save.

When I want to abort, I usually just add a bogus field:
abort: true

then when jira rejects the bogus message I say "n" to the prompt.

I now check to see if the file has been modified from the original presented to the editor and abort the operation if I detect no changes. See (e69b65c)
