Support Forums: Add an indication of "Site URL" link for logged-out users

[SergeyBiryukov]

#363 added a "Site URL" link displayed under support topics. The link is currently only displayed to logged-in users, as per comment:11:ticket:363.

One of ru_RU moderators suggested some further improvements:

• There should be some indication of the link for logged-out users, for better context. Otherwise, the discussion is not fully clear unless you log in and then suddenly see the link. The indication could be the URL itself (if made open for everyone) or just an icon with a notice like "URL only available for logged-in users".
• There should be an indication of the link for RSS readers as well. Some people (including moderators) follow the forums via RSS and could ask for the link without knowing it's already there.
• The link should be renamed to "URL to the problem" or something along these lines.

In technical terms, the "Site URL" link is not any different from any links in post content, so maybe it could be a regular nofollow link as well, open for everyone?

Per ​discussion at the latest meeting in #forums:

• There should be a "Link only available for logged-in users" notice for logged-out users and RSS readers.
• The link should have consistent labels:
  • In the post form: "Link to the page you need help with:"
  • Under topic text: "Link to the page I need help with:"

Going with a shorter label and notice under topic text:

The page I need help with: [log in to see the link]

where "log in" links to the login form.

Support Forums: Add an indication of the link to the page topic author needs help with for logged-out users.

Change "Site URL:" label to "The page I need help with:".

Fixes #3049.
