Message:

1. Added moveMetaXMLToCSV 2. Both this and exportMetaAsCSV now also made to work for the remote case. 3. Bugfix to oversight in GUIManager that in the previous commit used to ignore user selected csvfile and always created a metdata.csv in import folder. 4. Tidied up MetaToCSV.java some more.
