Add some bitmap images to our zipfldr shell extenson. MS version of this has them, but our one currently hasn't. And I think without bitmaps the wizard dialogs look a bit incompleted.
I made them similar to MS bitmaps. They have exactly the same size (height x width), but looks differently, in ReactOS Tango style. CORE-17092
Extraction happens now in its own thread, allowing for cancelling in the middle of extraction or moving the window during the extraction.
File extraction was previously happening in the main thread, freezing the whole window until the end. Now when the user clicks "Next", a new thread is created and the extraction starts from there, allowing to move the window during the extraction, or to cancel the extraction in the middle. (Note: after clicking "Cancel", extraction continues until the current file is extracted).
