Add optimized config.json to each test app

There's a number of ways to speed up Alloy compile time. 2 simples ones are setting the following values in the config.json:

{

  "sourcemap": false,

  "adapters": []

}

This will skip the sourcemap step and won't include any sync adapters. Each test app should be evaluated based on its needs and have an optimized config.json to make the automated test suite run as quickly as possible.
