This update fixes small issue in uninstallation when it is done via cmd.php that was missed in previous update released an hour ago.
This update changes code in installation/uninstallation process:
Code injected in src/config.php will not crash XenForo even if add-on files are deleted but line in config.php is not removed.
During uninstall add-on will attempt to remove its code from src/config.php if its writable.
Also add-on links to following Gist to explain installation/uninstallation process in case if src/config.php is not writable: https://gist.github.com/cyberalien/b3295a0392d92ce159f59da6e138f858
