Bugfix and Feature Addition

[csquared]

Hi Brendan:

I added a check in the format overriding to only override :html formats so :js and :xml will get through.

Also, I created another top level function that enables the plugin without setting the before_filter so you can set the before_fitler by hand if you want more fine grained control.

If you want me to send a pull request for just one of these commits let me know.

Cheers,
Chris

I've no strong opinion on the second two commits here, but fd6f9fa is an absolutely crucial bugfix for our application as well.
