Add zero-width space to person/community's shown name

[Snow4DV]

Addresses issue #775 - last word of community's name is cut if instance's URL is too long. I added zero-width space so it would cut name of instance only if it doesn't fit.

This works

Well there you could change the Overflow to show the dots instead of cutting it off if that change in behavior is wanted. But doing the above change there is much harder.

I think you're right - it's better just to change overflow in CommunityName to "overflow = TextOverflow.Ellipsis". In that case it will be eaiser to distinguish local communities from remote ones if such thing happens
