Fix cases where Markdown did not render links in activity feed

HTML would be stripped in `truncate_if_block` when a comment had multiple lines
and the first wasn't long enough to be truncated. The use of `node.content` would
strip all HTML tags. Using `node.inner_html` retains these tags and puts the
"..." in between paragraph tags.

Fix user identities API

Added ability to update or set the identity of an existing user, like the documentation said it was possible, but actually wasn't.

@DouweM or @stanhu could you please take a look at my code, and see if its sound?

HTML would be stripped in `truncate_if_block` when a comment had multiple lines

strip all HTML tags. Using `node.inner_html` retains these tags and puts the

Closes #2586

Prior, because the link "api/README.md" was matched twice, the first
link became "help/help/api/README.md". Now we do a negative lookahead to
make sure the link doesn't start with `help/`.

This fix is still not ideal, see TODO note.

Clarify confirmation text on user deletion.

See #1699

Some users thought it was ok to delete the user because they'd only use the issues.  
This clarifies a bit better what's being deleted when you delete a user.
