Add option to open URLs on click

This adds the option to automatically launch URLs with a specified
program when clicking on them.

The config option `mouse.url_launcher` has been added to specify which
program should be used to open the URL. The URL is always passed as the
last parameter to the specified command.

This fixes #113.
