Garbage string removal
Added support for fieldname__csvValue() method to format field output for use in CSV exports.  Also added docs to the DelegateClass interface stub for this method.
Changed CSV value feature to use csvValue() rather than csv().
Fixed issue with export_csv only loading previews of records. It should load full records.  This had been broken a while back when it was changed to use the Dataface_RecordReader() for loading the records.
Also fixed order of columns in CSV to respect order assigned in fields.ini file.
Added support for boolean expressions as function arguments in the SQL parser.
