- add support for moving files on source to match dest (only for sync mode, still defaults to moving on dest if unsure)
- fix access denied errors on removing and overwriting files
- don't update database if the copy/move/delete failed
- crc verification on new files that fail will have a size of 0 in the database regardless of actual size
- a crc verification may fail even if the file was copied correctly, this only happens if using attr(+) mode and the crc for the source file in the database is out of date (eg. due corruption since the last scan)
- add propagate sync deletions flag to gui
