Changing resource file encoding from UCS-2 to ASCII to avoid binary patch creation for them

Processing the files in VS (by adding and removing a 'String Table' item from the `String Table → Open` dialog and saving the file) to avoid subsequent such processing
Reading rotate (along with the other PnS presets) from [Settings\PnSPresets]
Adding next P & S preset key

Adding P & S preset OSD message
Adding delete file key and playlist context menu option

The deletion is confirmed by the move to recycle bin dialog

Playback goes to the next file when the command is called

The command is useful when many files are to previewed and deleted from a big playlist, because a series of manually repeated tasks to delete the currently playing file are wearying
Changing the single-instance OnCopyData IPC so that it waits for the new process to perform a time consuming task such as recursing through a large folder tree or multiple folders rather than resetting the playlist after a fixed amount of time

OnCopyData was previously limited to 500 ms but now has no limit

The ID_FILE_CLOSEMEDIA is removed because it causes a long delay between WM_COPYDATA messages, causing the playlist to reset. If it has to be there the allowed delay between WM_COPYDATA messages has to be increased to at least 2000 ms
