Rundowns with &, ?, + etc. will make router.get('/changeItemData'... break

[Dan-Shields]

URL query params are used for the changeItemData endpoint, and without URL encoding in the browser and then URL decoding on the server, some special characters will cause it to fail to find the rundown file.

I will keep these here as a reminder for a future update. Thanks for pointing this out!
