Enhanced robustness in retrieving the example input and in the init (at reboot) script.

The server errored out if the database was empty and there came a request, as it didn't check for empty arrays in dbparse.js in the function getRandomIndex. Fixed by adding handling & recursion limit. Added in init.sh a check to see if logging in to MySQL is possible to prevent errors at startup.
