fix: replace bad reverted code change; allow js rate headers
Last commit included an incorrect undo. I was going to move the Allow
header/output format parsing earlier in the dispatch method. But I
reverted it incorrectly and removed it instead. It has been added back
in the former location.
Header that allows javascript access to the rest rate limit header has
been moved. The rate limit headers can be accessed by client side
javascript regardless of the rate limit being exceeded.
