Improve disable-newtab-links - allow to prevent specific link #579

Currently it prevents opening new tabs and windows only if there is target attribute in element.
Sometimes target attribute can be used in legitimate links, so I think that it would be nice to have an option to prevent only specific links.
Something similar like in prevent-window-open with ability to use ! as negation - https://github.com/AdguardTeam/Scriptlets/blob/master/wiki/about-scriptlets.md#prevent-window-open

Example case:

function simulateModifiedClick(url) {
 try {
 const link = document.createElement("a");
 link.href = url;
 link.rel = "noopener";
 link.onclick = e => e.stopPropagation();
 document.body.appendChild(link);
 link.dispatchEvent(new MouseEvent("click", {
 bubbles: true,
 cancelable: true,
 view: window,
 ctrlKey: true,
 metaKey: true,
 button: 0
 }));
 link.remove();
 } catch {
 // Do nothing
 }
}
simulateModifiedClick('test');

So for instance, #%#//scriptlet('disable-newtab-links', 'test') should allow to prevent all links with test.
