Backupy

- 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file was copied correctly, this only happens if using attr(+) mode and the crc for the source file in the database is out of date (eg.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

- add ability to propagate deletions during sync
- add unique-ids for each folder so that files can properly be tracked for folders that sync with more than one other folder
- add configuration option to also write the log to destination
- don't display unnecessary status bars and notifications for empty transfer lists
- still write log if database fails to write
- fix gui overriding compare mode when loading config

- fix for checking if the log is open and locked by another program on windows
- can now type 'skip' during confirmation prompt to select specific files to skip
- made it easier to monkey patch the copy function: **backupy.fileman.FileManager.copy_function**
