[Mono-list] Nunit2 tests for corlib

[Nick Drochak]

All,

I've committed changes needed to get the corlib unit tests to run on nunit2
on MS.NET.  Under mono on Linux, however, nunit-console doesn't run yet.

On the surface it looks like either we've got some Security classes that are
buggy or unfinished or else maybe the problem is directly in the creation or
usage of AppDomains.

I'll be trying to get the tests to run on mono on linux, but would love to
have some help from others.

Enjoy,
Nick D.
