Enhancements to installer builder:

-  added a new zipdll.nsh that needs to be copied into the NSIS/include dir and should fix download and extract sample data functionality
-  updated readme file
-  it now expects the qgis binaries to be packaged to exist in c:\Program Files\qgis<version>
-  set the PRODUCT_VERSION_NUMBER before running
This will allow having multiple development versions on the same machine and being able to package them without issue.

 Follow the instructions on that page before
 attempting to run the installer.
