New constants and configurations
Added back file OldDocNewURL
I thought that file OldDocNewURL was not needed, then I commited a remove
file from staged and repository at all, but when trying to compile the
solution it complained that file was missing. I then try to load the file
in Solution and VS recovered file from somewhere, magically, added an
space and change modification date field, saved and file was totally
recovered.
