New track type lorax: details page embeds Lorax multi-tree viewer.
The trees are subtrees of an Ancestral Recombination Graph (ARG).
This commit also adds a track with 1000 Genomes data, tgpLorax.
The details page uses an iframe to embed the Lorax viewer from
a separate server (most likely will run in a docker container on
the GB server hosts; that will make this track more complicated for
mirror operators than other tracks).
