[Gimp-web] jaleco.com mirror domain update

[Nicola <nicola jaleco com>]

Hello, I'm the mantainer of the mirror https://mirror.jaleco.com/gimp

The mirror is now also exposed through https://mirror.download.it/gimp:
moreover, in about a week, we will issue a 301 from
https://mirror.jaleco.com/gimp/* to https://mirror.download.it/gimp/*

Please let me know if there are any issues, thanks



Nicola
