Rewrite rotating peer marquee logic to have constant speed

[brannondorsey]

The speed quirk in the current implementation is fine to show the project in the context of an art installation because the page is rarely refreshed. For an online version we should probably fix this though. My thought is that we could have a constant speed but have the text constantly wrap around without spacing. E.g.

# currently it works like this
[start] ip_1 | ip_2 | ip_3                                  [end]
# it could work like this
[start] ip_1 | ip_2 | ip_3 | ip_1 | ip_2 | ip_3 ip_1 | ip_2 [end]

Out of scope.
