Download builder should include build version in output

[jaredstehler]

The download builder on canjs.us (and also jquerypp.com) currently outputs a js file which doesn't contain the build version, which would be quite useful. For example, the jquery-ui builder does this (at least as of 1.10)

It also includes the selected components, which is really helpful when upgrading to the latest version of the library.

Here's the output of jquery-ui's builder:

/*! jQuery UI - v1.10.1 - 2013-02-23
* http://jqueryui.com
* Includes: jquery.ui.core.js, jquery.ui.widget.js, jquery.ui.mouse.js, jquery.ui.position.js,     jquery.ui.autocomplete.js, jquery.ui.datepicker.js, jquery.ui.menu.js, jquery.ui.slider.js

@alexisabril Can we somehow have the builder run the normal build Grunt tasks but parameterized? That way it would include code formatting and strip out the multiline comments, too.

Targeting for version 1.2 for now.

We're working on a new download builder that will include the header, clean up the code and also provide a minify option. Here is an example download how it will look: http://bitbuilder.herokuapp.com/can.custom.js?plugins=can/control&plugins=can/observe
