Subject: Distance in nearby tab (draft)

https://megapahit.com/show_bug.cgi?id=49
Still needs to be tidied up. For now it's aligned to the left.
If you want to align it to the right, apart from modifying
avatar_distance in panel_avatar_list_item.xml to look more like
last_interaction, modify newview/llavatarlistitem.cpp line 555
to be something like:
`S32 avatar_distance_width = avatar_item->mLastInteractionTime->getRect().mLeft - avatar_item->mAvatarDistance->getRect().mLeft;`
I had tried this at first, but I couldn't make it look good and
that's why I aligned it to the left.

Also, these distances need to not be shown on Friends list.
I'm doing that next.
