Title: Adding support for custom commands defined in simon.json

This way if we add any new dependencies or build steps, we can easily add them to `simon start`, or create custom commands like `simon refresh`.

To maintain backwards compatibility I'll add existing tasks as defaults to the base `simon.json`. It'll have one new field that looks like this:
```json
{
"tasks": {
"start": [...],
"install": [...],
"refresh": [...],
"update": [...]
}
}
```

Each member of tasks will look something like like this

```json
{
"update": [{
"command": "npm",
"args": "update"
}, {
"command": "composer",
"args": ["update"]
}]
}
```

Where `command` is one of the available commands from `simon help`, and `args` is the array/string of parameters for that function.
