The addition of external link warning has changed the behavior of
opening links from opening in a new tab to opening in the same tab.
This restores the old behavior and opens all links in a new tab.

A malicious user could modify a valid looking link (for example of the editor UI)
to point to a malicous site, by using overlays and CSS. Since CSS should stay
enabled, we need to make the user aware of possible risks when leaving the
HedgeDoc instance, in order to protect them from credential-theft.
This commit adds a new interstitial page for external links, that shows the
target URL and asks the user, whether they really want to continue.
