First half of work on output filename masks is done
As part of rewriting the Batch file processing screen, I've been looking closely at the clunky old system by which the results of files were saved to a designated location and name. I'm going for a placeholder-based system similar to that used in oXygen's transformation scenarios, but a bit more flexible (it has more human-readable placeholders, and has one for the original file extension). This also integrates with controls for choosing an actual folder as part of the filename. I have most of the work done, but there are some GUI issues to fix -- I need to add a plain folder image to the Nuvola dll, add images to the popup menu, and figure out a problem with the position of the display of the popup menu, which is currently in the wrong place. I've also refactored a lot of the original code, renaming components to remove the leading "u" which was used to designate a TTntUnicodeControls component.
