Julian Prieber 89f8361edd Added security check tool
Added new security check tool. This tool is a new page that displays diagnostic information about your LittleLink Custom installation.

Previously, installing LittleLink Custom on NGINX or other platforms that do not support .htaccess functionality presented a significant security risk if not configured properly. This tool simply shows if critical system files can be accessed externally by anyone. In addition, information about writing access to important files or directories is displayed here.
