POST's should not require default params

[bdunklau]

I was asked to create this issue after submitting this question http://groups.google.com/group/angular/browse_thread/thread/bb21293203c7c68f#

Apparently, when creating an angular.service, you have to specify default params in the second argument of $resource in order for the @-style POST parameters to be evaluated. If you don't specify default params, then your @params will be passed to the web server as literals as my post above shows.

When a default value of a param is prefixed with @ it reads the value from the Resource instance object.
It works fine with default params for all actions:

$resource('some/:param', {param: '@readFromObj'});

However it does not work with defaults specified per action:

$resource('some/:param', {}, {post: {params: {param: '@readFromObj'}}});
