Change deploy script to detect release version

[delphidabbler]

Deploy.bat requires the release version number to be entered on the command line. This is a potential source of error since the version passed on the command line could be different from the actual version number in the exe file resources.

Change this so that it extracts the correct version information from one of the exe files.

May need to change the format of the ProductVersion version info string to make this work.
