Improve how the user sees links in messages

I'm not a big fan of seeing URL's in text messages in STK.
It makes the message unnecessarily long.
And it's not very clear that the user is able to click the URL to open the link in the default web browser.

Example from Settings > Controls :

Connect your wiimote to the Bluetooth manager, then click on Ok. Detailed instructions at https://supertuxkart.net/Wiimote

I would prefer something like this:

Connect your wiimote to the Bluetooth manager, then click on Ok.

[Detailed instructions](https://supertuxkart.net/Wiimote)

"Detailed instructions" is the link text.
The URL is not visible.
A tooltip could be shown on hover. Perhaps with the URL or a text like "Open in default web browser".
Improve the styling of links so it's clear that the link can be clicked. E.g. better coloring, perhaps underline on hover, perhaps an icon in front or after the link.
Have links on a line of their own. Perhaps always at the bottom with 2 newlines before it so it's seperated from the message.

When starting STK sometimes this messages appear at the bottom as a tip:

You can visit https://supertuxkart.net/ for more information about the game.

The URL is regular text (not a link) so the users can't click it and only appear for a limited time.
