Module Params' proposal import syntax

I previously implemented the syntax in "Proposal: Module and Package Changes" [1]:

```
import [map, map2] from JsonDecode as JD
```

However, we decided [2] to use the one that appears in "Proposal: Module Params" [3]:

```
import JsonDecode as JD exposing [map, map2]
```

The new implementation also now supports comments and newlines between all the tokens.
