Support for hyperlink conversion

[fleschutz]

I propose the following new feature:

Whenever there is a "http://..." or "https://..." output in the console, this is converted automatically to a hyperlink. It's OK if this feature is off by default and needs to be enabled.

Clicking on that hyperlink should open the Web page in a new tab by default. As an option no new tab is opened, maybe depending on the configuration or what kind of modifier is pressed.

Use case: CLI programs sometimes print URL's (to the homepage, to manual pages, to error message details, etc.). Clicking on those URL's is intuitive, without the need for a slow copy & paste.
