Upgrade.bat does nothing for 1.16.0

Many thanks to the PgAdmin team for their years-long dedication to 
providing a top-notch end-user grahical tool for PostgreSQL.

I normally simply run the MSI file to upgrade from one version to the 
next.  This time, I decided to try the supplied upgrade.bat to see what 
if anything it did differently; I thought maybe it provided a hands-free 
upgrade.  Unfortunately, it didn't do anything for me (Windows 7 64-bit, 
current on all updates.)  I ran it, and it showed the setup program.  I 
got the popup from Windows asking me if I wanted to allow this program 
to make changes to my computer.  Once I clicked Ok, the setup window did 
something for about 3 more seconds and closed.  When I started PgAdmin 
from the start menu, version 1.14 was still installed.
