[saas3][Website Builder][Menu-URLs] URLs are case sensitive but should not be!

[LisAndi - Andi Becker - http://lisandi.com]

1
By default a Menu Title with a Capital Letter at the beginning will result in a URL with Capital letter
If now someone typs an URL with small letter (what is the common way to do it) you page can't be found
2
Even worse even when you change it later it won't be found!!! Probably because of caching - in that case the cache where URLs get changed needs to get automatically be deleted and build up new.
