Add JavaScript asset-transfer-basic application

While the TypeScript application sample is essentially identical (with
the addition of some type declarations), there seems to be sufficient
uncertainty amongst JavaScript developers not familiar with TypeScript
on how best to implement a JavaScript application that it is worthwhile
having one plain JavaScript sample using the current client API.

 ## Clean up
 
 When you are finished, you can bring down the test network (from the `test-network` folder). The command will remove all the nodes of the test network, and delete any ledger data that you created.
