VPX File Swapper

Background:

As authors migrate from VPX 10.6 to 10.7 (and beyond), keeping a working copy of both installs is ideal, but impractical.
At time of writing, with all but one table (the excellent Escape from Monkey Island by remdwaas1986), users can get away with just copying the VPX 10.7 executable file as per https://www.youtube.com/watch?v=8hHtfLLt2dc&t=1954s.
However, with the (again excellent) Escape from Monkey Island (and, again, by remdwaas1986), table developers are starting to take advantage of features in files other than the executable (in the case of Monkey Island, bass.dll) from the more recent version(s) of VPX.

Enter VPX File Swapper, a simple `bat` file that can standin for your VPX 10.7 executable (in Popper or other frontend),
backup any 10.6 (or other) file(s),
swap for any 10.7 (or other) file(s),
run your VPX 10.7 (or other),
and then swap the files back in time for your next table.

Opinionated Instructions For Those Who Just Want To Get Monkey Island And Harry Potter Working:

5. Configure your frontend of choice to run `VpinballX07.bat` on VPX 10.7-specific tables. No customization is needed for VPX 10.6 tables. For Popper, this means setting your `Alternate Launcher` to `VPinballX07.bat` as per
