Emails: Allow the ability to only reinstall certain emails

[r-a-y]

Spawned from comment:4:ticket:7034, I thought it might be beneficial to reinstall certain emails.

This would be handy if we wanted to force an update to a specific email type and this functionality is also useful for plugin developers.

The changes to the likes of bp_email_get_type_schema() will be stomped on by the proposed patch in #6932, which I hope to get into 2.6. I don't know if we'll have time to 2.6 this, I probably won't, but let's be optimistic for a bit.

I also need to run this patch to understand some of the change in bp_admin_reinstall_emails, specifically adding the tax_query. It looks like it's there to only delete email posts that have a email type term assigned to them. Which, again, is probably okay, but it looks like it's a change being sneaked in with this one ("to reinstall emails").

okay #6932 got in. @r-a-y do you want to refresh / update this patch for that?

We're closing this ticket because it has not received any contribution or comments for at least two years. We have decided that it is better to close tickets that are good ideas, which have not gotten (or are unlikely to get) contributions, rather than keep things open indefinitely. This will help us share a more realistic roadmap for BuddyPress with you.

Everyone very much appreciates the time and effort that you spent sharing your idea with us. On behalf of the entire BuddyPress team, thank you.

If you feel strongly that this enhancement should still be added to BuddyPress, and you are able to contribute effort towards it, we encourage you to re-open the ticket, or start a discussion about it in our Slack channel. Please consider that time has proven that good ideas without contributions do not get built.
