Clone minoredit to enotif_minoredit

I don't actually know how many wikis are affected by this issue, just that enwiki is. I'm not doing this to enable a new enwiki customization, but to un-break email (which was just enabled for minor edits); it was already customized.

If I understand you correctly, the alternate suggestion is:

1. Define an 'editpage_minoredit' message, which is disabled by default (e.g. defaulting to '-').
2. On the edit page, if 'editpage_minoredit' is defined, use it. Otherwise, use 'minoredit'.
3. Always use 'minoredit' for emails.

I think that would work, except if someone used qqx on the edit page, it would show 'minoredit'. So unless they consult qqq or the source code, they'll never know 'editpage_minoredit' exists, and will likely still override 'minoredit' (breaking email).

So exporting and re-importing would be helpful. Thanks.
