can.stache will import components it depends on

[justinbmeyer]

Related to #1386, can.stache templates should be able to import components and modules they depend on.

For example, if a stache template looks like:

<div><can-slider></can-slider></div>

It will be transpiled to import can-slider.

Also, a template might depend on helpers. These can be imported like:

<import from="my/helpers">

It's possible that a component's name doesn't match it's moduleName. We can also support the following:

<import from="components/slider" as="can-slider">
<can-slider></can-slider>

In this case can-slider will not be imported, only components/slider.

Other

• This will only happen for templates loaded with the can/view/stache/system extension.
• It's possible that we eventually support this happening with progressively loaded templates. However, can.view will need to support promises.
