Updates .loader interface

• Now the .loader function assumes you are making a postgrest request.

To keep backward compatibility, just remove the second parameter from all your function calls to m.postgrest.loader. If in any case you`re not issuing a postgrest request, you should use your own loader implementation.

New paginationVM interface

• paginationVM contractor now takes a third argument to configure headers

This changes the order of parameters, so if you were using authenticate = false in some paginationVM you should pass an appropriate extraHeaders.

To keep backwards compatibility just add a third parameter {'Prefer': 'count=exact'} to every paginationVM call.

Now the order function in filtersVM is chainable
