Detect when a script file is an es2015 module created by
a transpiler like Babel or TypeScript and use the `default`
export instead of `module.exports` in such case.
The following artefacts support the new syntax now:
- boot scripts
- components
- middleware
- model scripts
Interpret model sources in the same way how `require.resolve`
interprets the path:
- values starting with `./` and `../` are relative to the file
where they are specified
- other values are relative to node modules folders
This way it's possible to specify a source `loopback/common/models`
and have it resolved to whatever place the loopback is installed.
LoopBack built-in models are special: they follow the loopback-boot
structure and provide `common/models/{name}.json` files, but they are
also automatically loaded (created) by loopback.
This change modifies `executor` to recognize built-in models and do not
redefine them.
