Allow users to set their own handlers for hyperlinks

[yusdacra]

Is your feature request related to a problem? Please describe.
I want to be able to handle link opening myself, such that I can use different code for different protocols, and other stuff like being able to open the link in a seperate tab on web, rather than the current tab.

Describe the solution you'd like
This could easily be implemented via just passing a closure to the hyperlink widget.

Describe alternatives you've considered
None?

Additional context
Nothing.

I think this could be implemented in another way:

If we add a new widget LinkButton that just takes a label (no URL) and does nothing on click, then you could do it yourself:

if ui.add(LinKButton::new("Documentation")).clicked() {
    …
}

It would look the same as HyperLink but have no click response, no url, and now hover text. Hyperlink could use LinkButton internally.

Yeah that would work better, more composition 😅
