refactor: allow object in default-process config field

It is confusing to the user why he cannot use an object for `default-process`:

```yaml
process:
  path: *.js
  enabled: true
default-process:
  enabled: false
```

I changed to internal representation of processes as well from boolean to the object. It is more explicit and more flexible should we add more information to processes.
