misc: support parent/clone relationship of devices "romof" support for device sets
misc: systems auto assign can detect empty software list folders in case they are named accordingly misc: software list import's default setting is off misc: changed behaviour of context menu "move all incomplete sets" to "move all sets with problems" (similar for delete). This also covers wrong named etc ones, not only missing files. misc: contextMenu options Delete/Move/Copy Current/all [not fixed]/all sets with problems use the parent set in full merged mode misc: cleaning cache also cleans hashes folder misc: batcher's scanner merge mode overwrite does not overwrite the information from a datfile's forcemerging option misc: batcher's rebuilder pack overwrite does not overwrite the information from a datfile's forcepacking option misc: don't stop multiple downloads on first failure misc: wrote a wrapper class to handle all filefind calls which weren't 32k path length ready. This should fix all remaining long path (32k) issues.
fixed: invalid wrong-case messages on chds with very long filenames fixed: wrongly list valid chds as unneeded when a no dump chd of the same name exists and 'mark no dump as unneeded' option is enabled
