Improved workflow (auto-create directories, quick save to sub directories, move/delete original file)

That's basically all the stuff I developed in several branches on my fork. While your program is the best for my purposes, it lacked some features that I really needed.

• Optionally auto-create missing directories
• Optionally show a dialog that allows you to save into one of nine sub directories, just with a button click or key press. I missed that, because only after having selected a cut, I know, if it is some action scene, a dialog, whatever. You can guess from the screenshot that it is especially useful for game recordings.
• Optionally delete or move the original file after the task was processed. If it is moved, the target can be an absolute directory or a sub directory of its original path.

I do not know how to work with translations, so it is all hard-coded English, currently.

To clarify this further, here are some screenshots:
