screendump now supports 64-bit versions of Windows

Written for screendump by Enrique Ramirez on 2009-07-19

Today I decided to add a 64-bit version of screendump with the 2.2.0.1 installer. The installer will automatically detect if you are running any 64-bit version of Windows and install the appropriate program. Users of 32-bit versions of Windows do not need to upgrade to 2.2.0.1. As usual, the source and installer are available at launchpad.
