Add a Verify build configuration

[ploeh]

Just like in the AutoFixture source code, a specific Verify build configuration will run Code Analysis, and treat warnings as errors, in order to provide a proper verification step before any sort of release build.

The purpose of a particular Verify configuration is that Code Analysis is slow, so we don't want it in the Debug configuration, and we also don't want it in the Release configuration, because I think it's sloppy to ship binaries with Code Analysis suppression attributes (a very subjective opinion, though).

We can close this now (the close button is not visible to me).
