fix(786) documentation says export instead of exports

[Anthony-Mckale]

I'm submitting a bug fix

Current behavior:

http://aurelia.io/hub.html#/doc/article/aurelia/framework/latest/bundling-jspm/9

{
"name":"jquery",
"path":"../node_modules/jquery/dist",
"main":"jquery.min",
"export": "$"
}
is incorrect

Expected/desired behavior:

{
"name":"jquery",
"path":"../node_modules/jquery/dist",
"main":"jquery.min",
"exports": "$"
}
as per http://requirejs.org/docs/api.html

What is the motivation / use case for changing the behavior?
avoid confusion for folks using old libraries

@JeroenVinke Can you confirm whether this change is correct or not?

Yep, looks good! I actually didn't notice this PR and made one myself for exactly the same: #816. That one i've closed so we can merge this
