Secure connection enforcement + Multi param model listing

Hi Evan, thanks for creating this (AWESOME!) plugin. I have been coding some small modifications to it for a project at home and think you might find them useful . 
-Added the posibility of listing all models with the requested attributes vi requesting
api/modelname?attrName=attrValue&attrNameTwo=secondValue
-Added the posibility to enforce secure connections (it can be specified per controller) by setting $httpsOnly var true or false.

Thanks again for working on this plugin, it has saved me hours of work.
Romina.
