$http get-request should append [] to name when arrays

[filipbech]

$http({
  url:'/api',
  params: {
    arr:[1,2,3]
  }
});

Currently gives you a get request to (wrong)
/api/?arr=1&arr=2&arr=3

should give you (expected)
/api/?arr%5B%5D=1&arr%5B%5D=2&arr%5B%5D=3
(when decoded its: /api/?arr[]=1&arr[]=2&arr[]=3)

Current workaround is to append [] to the attributename like:

params: {
  'arr[]':[1,2,3]
}

but that seems weird and broken?

This is duplicate of #3740 which is going to be solved in the 1.4 time-frame.
