Deep-linking

[ralphbean]

Visiting https://apps.fedoraproject.org/#koji should show you the koji leaf of the tree.

This will require some $(document).ready(...) js to read that URL token and make a call to the jit to set the tree state.

We should handle the "other direction" too: if you click and navigate over to the "bodhi" leaf, then the #fragment should be updated to /#bodhi (so people know you can do this.)
