The user can add `terminal-onclick-url-open` entry to `termux.properties` file to enable opening url links in terminal transcript on click or on tap. The default value is `false`. So adding the entry `terminal-onclick-url-open=true` to `termux.properties` file will enable url opening. Running `termux-reload-settings` command will also update the behaviour instantaneously if changed.
This commit just adds the property and doesn't implement the functionality. That will later be merged from #2146.
