static ilObjExercise::_fixFilename (   $a_filename)

This function fixes filenames.

Prior to ILIAS 3.10.0 filenames have been stored with full path in exc_returned.filename, e.g. /opt/ilias/my_client/exercise/547/157/20070813113926_README.doc

Problems occur, if the server is moved from one location to another. We do the following: The filename will be parsed and if it contains the string "/exercise/" we truncate everything before "/exercise/" and replace it with the current CLIENT_DATA_DIR.
