Colladoc changes format of comments

The merged-in comments from colladoc have use slightly changed formatting rules which pollutes changes sets and makes merging hard.

The format is changed from 

``` scala
/**
 *
 */
```

in the Scala library sources to now

``` scala
/**
  *
  */
```

Even if this may be the more reasonable format, Colladoc should follow the projects standards to make working with VCS not unnecessary hard.
