Link URL tooltips

[PierceLBrooks]

This pull request will push a textual tooltip onto your cursor whenever you hover over a link within the HTML document that shows the actual URL that it links to.

Thanks for this PR!

Some thoughts:

• Maybe it would make more sense to just name attr to tooltip, because that's all the variable does
• I personally would like if there was a switch in the config to globally enable or disable href tooltips
• With your mouse entered approach we could also allow for any element that has el->get_attr("tooltip"); attribute to show a imgui tooltip. So the user is not restricted to hrefs and in case of hrefs can even overwrite what is shown as tooltip.

What do you think?

Hi @BigJk ,

These are solid suggestions, so I went ahead and included appropriate accommodations for them in my most recent commit ( https://github.com/PierceLBrooks/ImHTML/commits/a9948a8ab640cf2bc75f4def44181d40f73ce8fc ). Additionally, there is now support for image alt-text attributes that is also toggleable by the corresponding new configuration member flag assigned onto each browser container instance, and I've verified bold-face font family behaviors during the course of verifying tooltip override functionality.

Thank you very much! Take care.
