Allow user to choose which email to be public

This commit allows user to show one of their emails in profile page,
or don't show email in this page.

This reverts commit 79b4d0b0, reversing
changes made to a1e147ce.

Revert "Merge branch 'fix_email_images' into 'master'"

This reverts commit d66148ef, reversing
changes made to cdb64a81.

This change needed to be reverted,
because not enough email clients support inline images.

/cc @DouweM As discussed before. I'll try to create a MR to allow access to all images this week. I'm a bit busy at the moment so no guarantees. ;)

Remove the invalid key factories

They're only used once each, and they're easy to build in-place.

See merge request !1766

Speed up the overridden `link_to` helper

Only bothers to check the provided link's external status if it's a String that doesn't begin with a path or anchor character.

I've run the entire spinach suite again locally and it seems to pass.
