Add flat classpath implementation for directories

There's added the flat classpath implementation for directories using
java.util.File directly. Since we work with a real directory - not
the AbstractFile - we don't need to iterate all entries of a file to
get inner entries of some package. We can just find an adequate
directory for a package.

There are added implementations for a class- and a sourcepath. Both
extend DirectoryFileLookup which provides common logic.
