Issue Type: DEFECT
Summary: scala-packages has to be backed by filesystem
as all/most of my projects live under the common package de.gorzala... i
thought i could just ommit the always empty folders "de" and "gorzala" and made
the following packages the root in filesystem. unfortunatly the scala-plugin
will than complain in source-editor for example at the import-statement that
the designated packages does not exist. when i resort to each scala-source file
in the folder of the package structure (as in Java) it stops complaining.
the scala compilier sees no problems for both cases.
