Allows middle-click and ctrl+click outbound clicks to properly open as user intended

[Vigasaurus]

Changes

Allows middle clicks or ctrl+click, cmd+click, shift+click to track to plausible, and open in a new tab if requested, instead of always redirecting the current tab.

Fixes #451

This will almost certainly cause conflicts with #489 in the compiled script, so I didn't push them in this PR at all. Once both are merged we can re-compile the merged version.

Nice way to account for middle clicks as well. Looks like formatting is a bit off and I'm curious what the purpose of window.open is when middle click or modifier is used.

[Vigasaurus]

So the reason for using window.open is that browsers interpret middle clicks as "Open in New Tab", the same as ctrl+click or cmd+click - and in the old way we'd always redirect the current tab to the new link. This way ensures that if a user does any of the actions that would normally redirect their click into a new tab (middle click, ctrl+click, cmd+click, or shift+click) - we open a new tab for the link as expected, as opposed to redirecting the current tab.

Nevermind, I see what you meant - we just don't prevent the default for the middle click or mod click. Will fix 👍
