MS changed Windows 7 "reg query" command to spit out fewer lines in its preamble
Annoyingly there is no option to print raw values and not this preamble.
So now using the Windows find command.
But this has the side effect of stopping this working with Cygwin as it uses its own GNU find command.
Might fix in the future but not simple since Windows find itself is in different locations
This allows region modules to register script functions that have more than a couple of arguments.
It also allows OpenSimulator code to use the feature and syntax additions that came with .NET 4.0
Windows users will need to install Microsoft .NET 4 framework if they have not done so already.
Windows C# Express 2010 also becomes the minimum IDE for build, so runprebuild.bat now generates a 2010 solution and runprebuild2010.bat goes away
Official minimum mono version becomes 2.10.8.1. OpenSimulator will probably work with 2.8 later but this is not guaranteed.
