fix(compiler): properly implement pure pipes and change pipe syntax 

Pure pipes as well as arrays and maps are
implemented via proxy functions. This is
faster than the previous implementation
and also generates less code.

BREAKING CHANGE:
- pipes now take a variable number of arguments, and not an array that contains all arguments.

* To create a Pipe, you must implement this interface.

* Angular invokes the `transform` method with the value of a binding
* as the first argument, and any parameters as the second argument in list form.
*
* ## Syntax
*
* `value | pipeName[:arg0[:arg1...]]`
*
* ### Example ([live demo](http://plnkr.co/edit/f5oyIked9M2cKzvZNKHV?p=preview))
*
* The `RepeatPipe` below repeats the value as many times as indicated by the first argument:
*
* ```
* import {Pipe, PipeTransform} from 'angular2/core';
*
* @Pipe({name: 'repeat'})
* export class RepeatPipe implements PipeTransform {
* transform(value: any, times: number) {
* return value.repeat(times);
* }
* }
* ```
*
* Invoking `{{ 'ok' | repeat:3 }}` in a template produces `okokok`.
*
