WinGui:

WinGui:
- Allow files to be dropped on the GUI executable. (Including shortcuts). This will automatically try to scan the file. Users can add their own registry entries to add an "open with" if they choose.
- Fixed an exception that occurs when a scanned file returns no titles.
- Fixed an issue where pressing "No" to the on close warning (when encodes are running) would cancel the encode anyway.
