ivatar vs. libravatar name on home page

Hello, I think we want the home page on https://libravatar.fedorainfracloud.org/ to say:

"libravatar" "freeing the web one face at a time"

instead of:

"ivatar" "freeing the web one face at a time"

I understand ivatar is the name of the software but i don't think users need to know the software is actually named differently.

Similarly, we should modify:

iVatar :: federated avatar hosting service

Maybe this can be done by adding a configuration variable SERVICE_NAME and using that in the template?
