NUnit is unable to launch tests under .NET 4.0

[Charlie Poole]

NUnit runs successfully under .NET 4.0 from the command line, by setting COMPLUS_Version=v4.0.20506. But when launching a test from the gui, net-4.0 is not an available option. Similarly, it's not a choice for the /framework option in the console runner.

We should make all installed versions of .NET available, including those that use the 2.0 CLR - net-3.0 and net-3.5.

A further note:

We should also make this available in under the Set Runtime submenu for Windows installs and under the reload menu in the Gui.

This bug can be split in case someone wants to be mentored on just one part of it - minus the installer stuff, for example.

Obviously, you have to have .NET 4.0 installed to work on it.

Fixed. A test assembly compiled with VS.Net 2010 using .Net 4.0 can be recognized and processed by NUnit with this fix.
