Fix orders not showing up in admin. (#153)

This change anchors the longclaworders API URLs with a '^' to ensure they can't
confusingly match 'ANYTHING/api/order/...'. Also forces the order loading
JavaScript to use an absolute URL.

I'm not sure that this is the best architectural solution, but it resolves the
issues I'm having at least.

Fixes #131.
