adjusts distinction barrier of QFS compression
migrates to Scala 2.11 and rapture-io 0.9.1

Particularly odd is the adjustment to PropertyParser. Without the
explicit declaration of return types, the compiler/typer would not
terminate with Scala 2.11. There was no such issue with Scala 2.10.
replaces FileUrls by java.io.File

This gets rid of the dependency rapture-fs. The reason for this change is
that Java's File is usually good enough and that there are still a few
issues in rapture-fs.
