This allows you to click/press directly on a URL in the terminal view to
open it. It takes priority over opening the keyboard, so if you click on
a URL it is opened, and if you click anywhere else the keyboard opens
like before.
Currently, if the application in the terminal is tracking the mouse and
you click on a URL, both actions happen. The mouse event is sent to the
application, and the URL is also opened.
To enable support for this, you have to set
`terminal-onclick-url-open=true` in `termux.properties`.
